gcj: hello world crash

gcj: hello world crash

[Henry Miller]

I've install gcj along with the rest of gcc34 on my FreeBSD 5.3 system
(Installed from the ports system, updated today), and built and ran a
simple hello world program.  Surprisingly it dumps core, failing in
_Jv_FindClass  (gdb output follows).  Obviously something isn't
installed right, but what?
