Sun for JDK 1.4.1. Pkgsrc changes include noting that some of the installed
files are config files and using bsd.pkg.install.mk to handle the file
copying and directory handling, and using a more scalable method to remove
files shared between the JRE and JDK during the JDK installation. Also,
the JDK 1.4.x series are now installed into ${LOCALBASE}/java/sun-1.4 so
that future updates of this package won't require a new JDK directory.
