Hi
After lurking on this list for many years, it's time I contributed.
Sun's Java under FC 8 is broken, and no Java apps that use X11 will run.
Error is
xcb_xlib.c:50: xcb_xlib_unlock: Assertion 'c->xlib.lock' failed
Other distros may have the same problem.
Sun claim it is a bug with XCB. XCB claim it is a long-standing bug with
Java. Fedora won't include a workaround that just warns about broken locks
instead of stopping. The problem seems to be Java making Xlib calls in a
sequence not allowed under the Xlib replacement XCB.
The only workaround that actually seems to work for me so far has been to
download and install the rpms
libxcb-1.0-3.i_acknowledge_that_my_jdk_is_broken.fc9.i386.rpm and
ibxcb-devel-1.0-3.i_acknowledge_that_my_jdk_is_broken.fc9.i386.rpm from
http://ajax.fedorapeople.org/libxcb/. Then run Java with export
LIBXCB_ALLOW_SLOPPY_LOCK=1. This replaces libxcb.1.0.3 with a version that
only complains instead of barfing.
