The IcedTea project added a PowerPC Java port (both 32 and 64 bit) of OpenJDK. IcedTea 1.5 now also tracks the mercurial repo, provides better GNU/Linux integration by using standard system libraries (libpng, libjpeg, zlib, giflib) and can be bootstrapped with the free gcj/ecj/classpath toolchain. OpenJDK just accepted a new porters group and Gary Benson wrote a guide to porting IcedTea that might be the start of a lot of other Java ports.

The more platforms it runs on, the the more people will run it. The more peple that run it, the better chance that bugs in closed source software as well as icedTea itself will be fixed.
I still haven’t had success building IcedTea on Gentoo but I keep trying. I think my issues are related to running in a hardened environment but I haven’t figured out what exactly is causing my build failures. With more people working on IcedTea now that it is ported I’m hoping these bugs will be resolved.
