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 Starting program: /usr/home/brian/openjdk6/freshv2.2/bsd-port6.modified/build/bsd-amd64/j2sdk-image/bin/jmap -finalizerinfo 118 (no debugging symbols found)...(no debugging symbols found)...[New LWP 104363] (no debugging symbols found)...(no debugging symbols found)...[New Thread 0x800b01120 (LWP 104363)] [New LWP 104363] Program received signal SIGTRAP, Trace/breakpoint trap.
