Zero is basically an easy to port Java interpreter that currently
supports, among many others, PowerPC (32- and 64-bit). See
http://openjdk.java.net/projects/zero/.

I suspect the version of Hotspot in the BSD port is old, which is why
Zero is not compiling.

Even when you get it to compile, the performance may be poor, as Zero
is just an interpreter. The related Shark project should be faster as
it uses LLVM's JIT, and it seems to support PowerPC.
