The FreeBSD Ports Collection already has 1.45 version of the Bouncy Castle and
this new port is based on java/bouncycastle.
Newer versions are not API-compatible with that older one. Some say they should
be given 2.x version numbers. So, this new version comes as distinct port
java/bouncycastle15 instead of update for existing java/bouncycastle15 to keep
old API version available.
This is neccessary dependency for other port updates, e.g. newer version of
iText PDF (devel/itext) requires new API of modern Bouncy Castle versions.
