It sounds like gcc was not installed in the same place as libgcj, or perhaps
it was not compiled correctly. gcj *should* be able to find its classes, but
if it can't you can use CLASSPATH to help it out.

Using gdb:

$ gcj -g --main=HelloWorld -o HelloWorld HelloWorld.java
$ gdb ./HelloWorld
"run"
"bt" when it crashes. Send us the output.

Is suspect your problem is the garbage collector. You may want to try a newer
libgcj snapshot, which has a new gc version and some PPC fixes.
