FYI, the problem with gcj on darwin9 is that FSF gcc now emits epilogue
notes in the _eh_frames which causes the system unwinder on darwin9 to
puke. Fortunately, when the compact unwinder was added in darwin10, the
old system unwinder was replaced with a compatibility unwinder which
tolerates the epilogue notes in _eh_frames. A patch for darwin9 was proposed
awhile back but never progressed into gcc trunk...
