Upstream changelog:
Tomcat 9.0.62 (remm)
Catalina
Add: Effectively disable the WebappClassLoaderBase.getResources()
method as it is not used and if something accidently exposes the class
loader this method can be used to gain access to Tomcat internals. (markt)
Tomcat 9.0.61 (remm)
Catalina
Code: Harden the CredentialHandler implementations by switching to a
constant-time implementation for credential comparisons. (schultz/markt)
Coyote
Fix: Use a constant for the default TLS cipher suite. This will allow
skipping setting it in some cases (for example, it does not make sense for
OpenSSL TLS 1.3). (remm)
Fix: #487: Improve logging of unknown settings frames. Pull request by
Thomas Hoffmann. (remm)
Add: 65975: Add a warning if a TLS virtual host is configured with
optional certificate authentication and the containing connector is also
configured to support HTTP/2 as HTTP/2 does not permit optional
certificate authentication. (markt)
Add: 65975: Add a warning if a TLS virtual host is configured for TLS
1.3 with a JSSE implementation and a web application is configured for
CLIENT-CERT authentication. CLIENT-CERT authentication requires
post-handshake authentication (PHA) when used with TLS 1.3 but the JSSE
TLS 1.3 implementation does not support PHA. (markt)
Fix: Improve the recycling of Processor objects to make it more
robust. (markt)
Jasper
Fix: 65959: Serialize Function as String[] rather Class[]. (remm)
Web applications
Fix: 65952: Align --add-opens configuration for jsvc with the current
Tomcat scripts. (markt)
Fix: Correct the AJP and HTTP/1.1 Connector configuration pages in the
documentation web application to show which attributes are applicable to
all Connectors and which are implementation specific. (markt)

with bnd 6.2.0. (markt)
Code: Refactor the resource files for the Apache Tomcat installer for
Windows so that all the resource files are located in a single directory
in the source tree. (markt)
Update: Update the packaged version of the Tomcat Native Library to

2022-03-14 Tomcat 9.0.60 (remm)
Catalina
Fix: 65921: The type substitution flag for the rewrite valve should
set the content type for the response, not the request. (markt)
Fix: #479: Enable the rewrite valve to redirect requests when the
original request cannot be mapped to a context. This typically happens
when no ROOT context is defined. Pull request by elkman. (markt)
Fix: 65940: Fix NullPointerException if an exception occurs during the
destruction of a Servlet. (markt)
Coyote
Fix: Fix regression introduced with 65757 bugfix which better
identified non request threads but which introduced a similar problem when
user code was doing sequential operations in a single thread. Test case
code submitted by Istvan Szekely. (remm)
Fix: Fix potential thread-safety issue that could cause HTTP/1.1
request processing to wait, and potentially timeout, waiting for
additional data when the full request has been received. (markt)
Fix: Throw IOException rather than IllegalStateException when the
application attempts to write to an HTTP/2 stream after the client has
closed the stream. (markt)
Jasper
Fix: When resolving methods in EL expressions that use beans and/or
static fields, ensure that any custom type conversion is considered when
identifying the method to call. (markt)
Web applications
Fix: Correct the name of the value attribute in the new documentation
of OpenSSLConfCmd elements. (rjung)
2022-02-28 Tomcat 9.0.59 (remm)
Catalina
Add: Add ha-api-*.jar and jaxws-rt-*.jar to the list of JARs to skip
when scanning for TLDs, web fragments and annotations. (michaelo)
Add: Expand the default mappings used by ServletResponse.setLocale()
to include a mapping from the ja locale to the Shift_JIS encoding. (markt)
Fix: 65806: Improve the handling of session ID generation when the
default algorithm for SecureRandom (SHA1PRNG) is not supported by the
configured providers as will be the case for a FIPS compliant
configuration. (markt)
Fix: #464: Fall back to the class loader used to load JULI when the
thread context class loader is not set. In a normal Tomcat configuration,
this will be the system class loader. Based on a pull request by
jackshirazi. (markt)
Fix: #469: Include the Java Annotations API in the classes that Tomcat
will not load from web applications. Pull request provided by ppkarwasz.
(markt)

TomcatPrincipal and GenericPrincipal. Patch provided by Carsten Klein.
(michaelo)
Fix: Fix a potential StringIndexOutOfBoundsException exception when
generating a WebDAV multi-status response after an error during a copy or
delete. Report the paths relative to the server root for any resources
with an error. (markt)
Fix: Improve the format of WebDAV XML responses to make them easier
for humans to read. The change ensures that there is always a line break
before starting a new element. (markt)
Fix: Improve validation of the Destination header for WebDAV MOVE and
COPY requests. (markt)
Coyote
Fix: Correct a regression in the fix for 65454 that meant that
minSpareThreads and maxThreads settings were ignored when the Connector
used an internal executor. (markt)
Fix: 65776: Improve the detection of the Linux duplicate accept bug
and reduce (hopefully avoid) instances of false positives. (markt)
Fix: 65848: Revert the change that attempted to align the behaviour of
client certificate authentication with NIO or NIO2 with OpenSSL for TLS
between MacOS and Linux/Windows as the root cause was traced to
configuration differences. (markt)
Fix: #467: When system time moves backwards (e.g. after clock
correction), ensure that the cached formatted current date used for HTTP
headers tracks this change. Pull request provided by zhenguoli. (markt)
Jasper
Fix: #474: Prevent a tag file from corrupting the ELContext of the
calling page. Pull request provided by Dmitri Blinov. (markt)

reduce the number of Java versions developers need to juggle. (markt)
Code: Use LF line endings for text files in JARs to support
reproducible builds across different operating systems. (markt)
Fix: Fix dependencies for individual test targets in Ant build file.
Based on #468 provided by Totoo chenyonghui. (markt)
Update: Update the OWB module to Apache OpenWebBeans 2.0.26. (remm)
Fix: Revert the cherry-pick of JavaDoc fix from DBCP applied in 9.0.57
that broke the DataSourceMXBean by using a type that isn't supported by
MXBeans. (markt)
2022-01-20 Tomcat 9.0.58 (remm)
Coyote
Fix: Correct a regression in the fix for 65785 that broke HTTP/2
server push. (markt)
not released Tomcat 9.0.57 (remm)

Fix: Make the calculation of the session storage location more robust
when using file based persistent storage. (markt)
Coyote
Fix: 65726: Implement support for HTTP/1.1 upgrade when the request
includes a body. The maximum permitted size of the body is controlled by
maxSavePostSize. (markt)
Fix: Restore pre-starting of minSpareThreads lost in the fix for
65454. (markt)
Fix: Revert the previous fix for 65714 and implement a more
comprehensive fix. (markt)
Fix: 65757: Missing initial IO listener notification on Servlet
container dispatch to another container thread. (remm)
Fix: Expand the fix for 65757 so that rather than just checking if
processing is happening on a container thread, the check is now if
processing is happening on the container thread currently allocated to
this request/response. (markt)
Fix: Improve the fix for RST frame ordering added in 9.0.56 to avoid a
potential deadlock on some systems in non-default configurations. (markt)
Add: 65767: Add support for certificates that use keys encrypted using
PBES2. Based on a pull request provided by xiezhaokun. (markt)
Code: Refactor testing whether a String is a valid HTTP token. (markt)
Fix: 65785: Perform additional validation of HTTP headers when using
HTTP/2. (markt)
Fix: When a Connector or Endpoint is paused, ensure that only new
connections and new requests on existing connections are stopped while
allowing in progress requests to run to completion. (markt)
Fix: Explicitly release ByteBuffer instances associated with pooled
channels when stopping the NioEndpoint and Nio2Endpoint. (markt)
Fix: Narrow the scope of the logging of invalid cookie headers to just
the invalid cookie rather than the whole cookie header. (markt)
Jasper
Fix: 65724: Fix missing messages for some
PropertyNotWritableExceptions caused by a typo in the name used for a
resource string. (markt)
Add: Add support for specifying Java 18 (with the value 18) as the
compiler source and/or compiler target for JSP compilation. If used with
an Eclipse JDT compiler version that does not support these values, a
warning will be logged and the default will used. (markt)
WebSocket
Add: Add support for POJO WebSocket endpoints to the programmatic
upgrade that allows applications to opt to upgrade an HTTP connection to
WebSocket. (markt)
Fix: 65763: Improve handling of WebSocket connection close if a
message write times out before the message is fully written. (markt)

used to avoid JVM crashes. (michaelo)
Fix: Refactor the AsyncFileHandler to reduce the possibility of log
messages being lost on shutdown. (markt)
Update: Refactor the AsyncFileHandler to remove the need for the
org.apache.juli.AsyncLoggerPollInterval. If set, this property now has no
effect. (markt)
Add: Add debug logging to the RestCsrfPreventionFilter. Based on pull
request #452 by Polina Georgieva. (markt)
Add: 65710: Implement a workaround for a JVM bug that can trigger a
file descriptor leak when using multi-part upload and the application does
not explicitly close an input stream for an uploaded file that was cached
on disk. (markt)
Coyote
Fix: Improve error handling if APR/Native fails to attach TLS
capabilities to a TLS enabled client connection. (markt)
Fix: Improve error handling if APR/Native fails to accept an incoming
connection. (markt)
Add: Provide protection against a known OS bug that causes the
acceptor to report an incoming connection more than once. (markt)
Fix: Avoid unnecessary duplicate read registrations for blocking I/O
with the NIO connector. (markt)
Fix: 65677: Improve exception handling for errors during HTTP/1.1
reads with NIO2. (markt)
Fix: Refactor APR/native connector shutdown to remove a potential
source of JVM crashes on shutdown when sendfile is used. (markt)
Fix: When an error occurs that triggers a stream reset, ensure that
the first RST frame sent to the client is the one associated with the
error that triggered the reset. (markt)
Fix: 65714: Fix exceptions when the security manager is enabled and
the first request received after starting is an HTTP request to a TLS
enabled NIO2 connector. (markt)
Add: Ensure that using NIO or NIO2 with OpenSSL for TLS behaves the
same way on MacOS as it does on Linux and Windows when no trusted
certificate authorities are configured and reject all client certificates.
(markt)
Fix: Avoid a potential deadlock during the concurrent processing of
incoming HTTP/2 frames for a stream and that stream being reset. (markt)
Other
Fix: Switch from Cobertura to JaCoCo for code coverage as Cobertura
does not support code coverage for code compiled for Java 11 onwards. It
also removes the need to use a single thread to run the tests. (markt)
2021-11-10 Tomcat 9.0.55 (remm)
Catalina
Fix: Improve robustness of JNDIRealm for exceptions occurring when
getting the connection. Also add missing close when running into issues
getting the passord of a user. (remm)
Docs: Add Javadoc comment which listeners must be nested whithin
Server elements only. (michaelo)
Add: Add support for custom caching strategies for web application
resources. This initial implementation allows control over whether or not
a resource is cached. (markt)
Update: Log warning if a listener is not nested inside a Server
element although it must have been. (michaelo)
Coyote
Code: Improve performance of Connector shutdown - primarily to reduce
the time it takes to run the test suite. (markt)
Fix: Refactor the APR/native connector shutdown to reduce the
possibility of a JVM crash during the connector shutdown. (markt)
Add: #457: Add a toString() method to MimeHeader to aid debugging.
(dblevins)
Add: Add experimental OpenSSL support through the Panama API
incubating in Java 17, with support for OpenSSL 1.1+. This no longer
requires tomcat-native or APR. Please refer to the openssl-java17 module
from the main branch for more details. (remm)
Fix: Fix APR connector stop so it correctly waits for the sendfile
thread, if any, to exit. (markt)
Fix: Do not ignore the error condition if the APR connector is not
able to open a server socket as continuing in this case will trigger a JVM
crash. (markt)
Fix: Fix a potential JVM crash when using the APR/Native connector
with TLS. A crash could occur if the connector was stopped whilst a
connection was performing a TLS handshake. (markt)
Jasper
Update: Regenerate the EL parser using JavaCC 7.0.10. (markt)
Fix: Fix a bug that prevented the EL parser correctly parsing a
literal Map that used variables rather than literals for both keys and
values. (markt)
WebSocket
Update: Add a new method WsServerContainer.upgradeHttpToWebSocket() to
align with the new method that will be available from WebSocket 2.1
onwards. (markt)

DataSourceUserDatabase, since it is always global. (remm)
Fix: Fix delete then create object manipulations with
DataSourceUserDatabase. (remm)
Fix: 65553: Implement a work-around for a JRE bug that can trigger a
memory leak when using the JNDI realm. (markt)
Fix: 65586: Fix the bloom filter used to improve performance of
archive file look ups in the web resources implementation so it works
correctly for directory lookups whether or not the provided directory name
includes the trailing /. (markt)
Fix: #451: Improve the usefulness of the thread name cache used in
JULI. Pull request provided by t-gergely. (markt)
Coyote
Fix: 65563: Correct parsing of HTTP Content-Range headers. Tomcat was
incorrectly requiring an = character after bytes. Fix based on pull
request #449 by Thierry Guérin. (markt)
Fix: Correct a potential StackOverflowException with HTTP/2 and
sendfile. (markt)
Fix: Further improvements in the management of the connection flow
control window. This addresses various bugs that caused streams to
incorrectly report that they had timed out waiting for an allocation from
the connection flow control window. (markt)
Fix: 65577: Fix a AccessControlException reporting when running an
NIO2 connector with TLS enabled. (markt)
Update: Reclassify TLS ciphers that use AESCCM8 as medium security
rather than high security to align with recent changes in OpenSSL. (markt)
Fix: Fix an issue that caused some Servlet non-blocking API reads of
the HTTP request body to incorrectly use blocking IO. (markt)
Jasper
Fix: Fix the implementation of MethodExpression.getMethodInfo() so
that it returns the expected value rather than failing when the method
expression is defined with the parameter values in the expression rather
than the types being passed explicitly to
ExpressionFactory.createMethodExpression(). (markt)
WebSocket
Fix: The internal upgrade handler should close the associated
WebConnection on destroy. (remm)
Web applications
Fix: Clarify the JASPIC configuration options in the documentation web
application. (markt)
Other
Fix: 65585: Update obsolete comments at the start of the
build.properties.default file. (markt)
2021-09-10 Tomcat 9.0.53 (remm)
Catalina
Fix: Enable Tomcat to start if an (old) XML parser is configured that
does not support allow-java-encodings. A warning will be logged if such an
XML parser is detected. (markt)
Fix: Change the behaviour of custom error pages. If an error occurs
after the response is committed, once the custom error page content has
been added to the response the connection is now closed immediately rather
than closed cleanly. i.e. the last chunk that marks the end of the
response body is no longer sent. This acts as an additional signal to the
client that the request experienced an error. (markt)
Fix: 65479: When handling requests using JASPIC authentication, ensure
that PasswordValidationCallback.getResult() returns the result of the
password validation rather than always returning false. Fixed via pull
request #438 provided by Robert Rodewald. (markt)
Code: Refactor the authenticators to delegate the check for preemptive
authentication to the individual authenticators where an authentication
scheme specific check can be performed. Based on pull request #444 by
Robert Rodewald. (markt)
Update: Improve the reusability of the UserDatabase by adding
intermediate concrete implementation classes and allowing to do partial
database updates on save. (remm)
Add: Add a UserDatabase implementation as a superset of the
DataSourceRealm functionality. (remm)
Fix: Make sure the dynamic Principal returned by UserDatabaseRealm
stays up to date with the database contents, and add an option to have it
be static, similar to the other realms. (remm)
Add: Add derby-*.jar to the list of JARs to skip when scanning for
TLDs, web fragments and annotations. (markt)
Fix: #447. Correct JPMS metadata for catalina.jar. Pull request
provided by Hui Wang. (markt)
Coyote
Fix: Correct a logic error that meant setting certificateKeystoreFile
to NONE did not have the expected effect. NONE was incorrectly treated as
a file path. Patch provided by Mikael Sterner. (markt)
Fix: 65505: When an HTTP header value is removed, ensure that the
order of the remaining header values is unchanged. (markt)

Add: Update the internal fork of Apache Commons Codec to fd44e6b
(2021-09-01, 1.16-SNAPSHOT). Minor refactoring. (markt)
Update: Add Apache Derby 10.14.2.0 to the testsuite dependencies, for
JDBC and DataSource testing. (remm)
Add: 65661: Update the internal fork of Apache Commons FileUpload to
33d2d79 (2021-09-01, 2.0-SNAPSHOT). Refactoring and code clean-up. As a
result of Commons File Upload now using java.nio.file.Files, applications
using multi-part uploads need to ensure that the JVM is configured with
sufficient direct memory to store all in progress multi-part uploads.
(markt)
Add: Update the internal fork of Apache Commons Pool to 2.11.1
(2021-08-17). Improvements, code clean-up and refactoring. (markt)
Add: Update the internal fork of Apache Commons DBCP to 2.9.0

application classes were not configured with the correct package. (markt)
not released Tomcat 9.0.51 (remm)
Catalina
Fix: 65411: Always close the connection when an uncaught
NamingException occurs to avoid connection locking. Submitted by Ole
Ostergaard. (remm)
Fix: 65433: Correct a regression in the fix for 65397 where a
StringIndexOutOfBoundsException could be triggered if the canonical path
of the target of a symlink was shorter than the canonical path of the
directory in which the symlink had been created. Patch provided by Cedomir
Igaly. (markt)
Add: 65443: Refactor the CorsFilter to make it easier to extend.
(markt)
Fix: To avoid unnecessary cache revalidation, do not add an HTTP
Expires header when setting adding an HTTP header of CacheControl:
private. (markt)
Coyote
Fix: When writing an HTTP/2 response via sendfile (only enabled when
useAsyncIO is true) the connection flow control window was sometimes
ignored leading to various error conditions. sendfile now checks both the
stream and connection flow control windows before writing. (markt)
Add: Add debug logging for writing an HTTP/2 response via sendfile.
(markt)
Fix: Correct bugs in the HTTP/2 connection flow control management
that meant it was possible for a connection to stall waiting for a
connection flow control window update that had already arrived. Any
streams on that connection that were trying to write when this happened
would time out. (markt)
Fix: 65448: When using TLS with NIO, it was possible for a blocking
response write to hang just before the final TLS packet associated with
the response until the connection timed out at which point the final
packet would be sent and the connection closed. (markt)
Fix: 65454: Fix a race condition that could result in a delay to a new
request. The new request could be queued to wait for an existing request
to finish processing rather than the thread pool creating a new thread to
process the new request. (markt)
Fix: 65460: Correct a regression introduced in the previous release in
the change to reduce the number of small HTTP/2 window updates sent for
streams. A logic error meant that small window updates for the connection
were dropped. This meant that the connection flow window slowly reduced
over time until nothing could be sent. (markt)
Web applications
Fix: 65404: Correct a regression in the fix for 63362 that caused the
server status page in the Manager web application to be truncated if HTTP
upgrade was used such as when starting a WebSocket connection. (markt)

Code: Refactor the RemoteIpValve to use the common utility method for
list to comma separated string conversion. (markt)
Code: Refactor JNDIRealm$JNDIConnection so its fields are accessible
to sub-classes of JNDIRealm. (markt)
Fix: Fix serialization warnings in UserDatabasePrincipal reported by
SpotBugs. (markt)
Fix: 65397: Calls to ServletContext.getResourcePaths() no longer
include symbolic links in the results unless allowLinking has been set to
true. If a resource is skipped because of this change, a warning will be
logged as this typically indicates a configuration issue. (markt)
Coyote
Fix: 65368: Improve handling of clean closes of inbound TLS
connections. Treat them the same way as clean closes of non-TLS
connections rather than as unknown errors. (markt)
Fix: Modify the HTTP/2 connector not to sent small updates for stream
flow control windows to the user agent as, depending on how the user agent
is written, this may trigger small writes from the user agent that in turn
trigger the overhead protection. Small updates for stream flow control
windows are now combined with subsequent flow control window updates for
that stream to ensure that all stream flow control window updates sent
from Tomcat are larger than overheadWindowUpdateThreshold. (markt)
Add: Add additional debug logging to track the current state of the
HTTP/2 overhead count that Tomcat uses to detect and close potentially
malicious connections. (markt)
Update: Many HTTP/2 requests from browsers will trigger one overhead
frame and one non-overhead frame. Change the overhead calculation so that
a non-overhead frame reduces the current overhead count by 2 rather than
1. This means that, over time, the overhead count for a well-behaved
connection will trend downwards. (markt)
Update: Change the initial HTTP/2 overhead count from -10 to -10 *
overheadCountFactor. This means that, regardless of the value chosen for
overheadCountFactor, when a connection opens 10 overhead frames in a row
will be required to trigger the overhead protection. (markt)
Update: Increase the default overheadCountFactor from 1 to 10 and
change the reduction in overhead count for a non-overhead frame from -2 to
-20. This allows for a larger range (0-20) to be used for
overheadCountFactor providing for finer-grained control. (markt)
Fix: Modify the parsing of HTTP header values that use the 1#token to
ignore empty elements as per RFC 7230 section 7 instead of treating the
presence of empty elements as an error. (markt)
Fix: Expand the unit tests for HttpServlet.doHead() and correct the
flushing of the response buffer. The buffer used to behave as if it was
one byte smaller than the configured size. The buffer was flushed (and the
response committed if required) when the buffer was full. The buffer is
now flushed (and the response committed if required) if the buffer is full
and there is more data to write. (markt)
Fix: Fix an issue where concurrent HTTP/2 writes (or concurrent reads)
to the same connection could hang and eventually timeout when async IO was
enabled (it is enabled by default). (markt)
Jasper
Fix: 65390: Correct a regression in the fix for 65124 and restore code
that was removed in error leading to JSP compilation failures in some
circumstances. (markt)
Update: Update to the Eclipse JDT compiler 4.20. (markt)
Add: Add support for specifying Java 17 (with the value 17) as the
compiler source and/or compiler target for JSP compilation. If used with
an Eclipse JDT compiler version that does not support these values, a

the initial TLS handshake. (markt)
Add: Let the RemoteCIDRValve inherit from RequestFilterValve and
support all of its features. Especially add support for connector specific
configuration using addConnectorPort. (rjung)
Add: Add peerAddress to coyote request, which contains the IP address
of the direct connection peer. If a reverse proxy sits in front of Tomcat
and the protocol used is AJP or HTTP in combination with the
RemoteIp(Valve|Filter), the peer address might differ from the
remoteAddress. The latter then contains the address of the client in front
of the reverse proxy, not the address of the proxy itself. Support for the
peer address has been added to the RemoteAddrValve and RemoteCIDRValve
with the new attribute usePeerAddress. This can be used to restrict access
to Tomcat based on the reverse proxy IP address, which is especially
useful to harden access to AJP connectors. The peer address can also be
logged in the access log using the new %{peer}a syntax. (rjung)
