Ivan Voras writes (19/02/2009) that he’d love to rewrite his finstall project (FreeBSD GUI Installer) in Java, which may result in license issue. OpenJDK would be  a much more preferable option:

OpenJDK looks like it might “soon” be ported to FreeBSD (though judging by the progress it looks like the official FreeBSD Java crowd is working on OpenJDK 1.7 which has not been released yet, instead of OpenJDK 1.6, which is).

Well, as of today, OpenJDK is available for FreeBSD.

For those unacquainted with OpenJDK, OpenJDK is an open-source implementation of the Java Platform, Standard Edition. Much of the OpenJDK code is licensed under the GPL version 2 with the Classpath exception. The Java Hotspot virtual machine source code is licensed under the GPL version 2 only.

This is a small step, but may have far reaching benefits.
