There is an infinitely long bugzilla about libxcb and the foolish asserts they added to it. At the moment, while waiting for an official fix, I enabled the development repo and updated libxcb from it, then set the environment variable LIBXCB_ALLOW_SLOPPY_LOCK="1" See bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=390261 (This breaks lots of code, not just java).
