This might work better.
gdb /usr/ports/java/openjdk6/work/langtools/make/java.core  
/usr/local/openjdk6/bin/java

It might be necessary to build java with DEBUG=true. Or at least  
FASTDEBUG=true. See 'make config' in /usr/ports/java/openjdk6.

BTW: I'm not sure, but I think your existing installation of openjdk6  
dumps core. This is important to know to debug the right program.

Regards,
Ronald.
