gdb and java

[Brian Gardner]

I've had success in debugging java using jdb, however this doesn't seem 
to support native debugging.  I'd like to use gdb but this doesn't work 
with (the error is bellow).  Currently I'm printing to stderr from 
native code but this is less than ideal and time consuming, any ideas?

# gdb jmap
(gdb) run -finalizerinfo 118
