Hello everytbody!
I recently installed NetBeans 6.1 from ports and noticed there is no
libprofilerinterface.so library for FreeBSD, and NetBeans complains the profiling
wouldn't work. I've downloaded the sources of NetBeans and was able to build the
libprofilerinterface.so from sources, once I placed it into the appropriate directory
NetBeans expects it to appear in - NetBeans stops reporting the error, however profiling
still doesn't work for some another reason - it just hands on the "calibration" stage.
I had built the module with -ggdb option, and found there is java.core file and
GDB shows this stack trace:

Does it makes sense for anybody? Is it possible to fix this somehow?
Thank you in advance!
