Well, all the gcj packages obviously require libgcj.  These are:

The ecj package is a gcj-accelerated version of javac:

kawa is a gcj-based LISP implementation:

sinjdoc is a gij-based version of javadoc:

OpenJDK, while technically correct, is not really fast enough to use on most
non-x86 systems.  We are working as fast as we can to get OpenJDK JIT-compiling
working on PPC systems.
