This is a known problem with Suse10.3 --- lots of things that use Java 
(e.g., Matlab) produce the same error message.  I'm currently trying to 
fix this upon my machine, but haven't succeeded yet.  Josh Triplett 
(http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6532373) suggested 
the following:

---begin---
I worked with jcristau and christoph4 via IRC on #debian-x, and we 
managed to
track down the problem with broken locking in Sun Java 1.5 and 1.6.  It only
occurs if Java finds the Xinerama extension, at which point it does 
something
broken with locking and triggers the assertion.  If Java never finds the
Xinerama extension, it doesn't trigger the assertion for broken locking.

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
---end---

You need to modify the path for your jre.  This seems to have helped 
several people.  But it didn't work for me.

A sure fix is going back to Suse10.2!  :(
