When starting my java application on linux, I have the following traceback:
Locking assertion failure. Backtrace:
#0 /usr/lib/libxcb-xlib.so.0 [0xc3e767]

It has already been discussed in a number of forums and bug reports:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6532373, or https://bugs.launchpad.net/ubuntu/+source/libxcb/+bug/87947
One possible work around seems to be to add the following variable setting when starting the application:
export LIBXCB_ALLOW_SLOPPY_LOCK=1
