Problems with graphical Java apps? This might help

[ivan-frankfurt]

After updating a 7.10 installation to Hardy Heron Alpha 4 I had a problem running graphical java applications

Locking assertion failure. Backtrace:
[..omitting the stack call]
java: xcb_xlib.c:82: xcb_xlib_unlock: Assertion `c->xlib.lock' failed.
Aborted (core dumped)

I could get the apps to work again with this (found on a SuSE forum)

export LIBXCB_ALLOW_SLOPPY_LOCK=1

Apologies if this is old news
