NOTABUG afaik.

This seems to be a bug with java

From Josh Triplett

The following workarounds address this problem:

For sun-java5-bin:
sed -i 's/XINERAMA/FAKEEXTN/g'
/usr/lib/jvm/java-1.5.0-sun-1.5.0.11/jre/lib/i386/xawt/libmawt.so

For sun-java6-bin:
sed -i 's/XINERAMA/FAKEEXTN/g'
/usr/lib/jvm/java-6-sun-1.6.0.00/jre/lib/i386/xawt/libmawt.so

The same fix (applied to the appropriate file) might work for other
proprietary JDKs.
