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.
