[solved] Java AWT/Swing: a warning message

hello,
whenever I run an application, which uses AWT or Swing GUI, java spits out this error message:

Locking assertion failure.  Backtrace:

however, the application runs and functions normally. Any Java expert there, who knows what this means? I have JRE and SDK installed.
I can just ignore it, but if I remember well, there was once upon a time a linux kernel update, after which this didn't happen and after another one it came back. a mysterious thing, isn't it? a race condition, perhaps...

Re: [solved] Java AWT/Swing: a warning message

sed -i 's/XINERAMA/FAKEEXTN/g' /opt/java/jre/lib/i386/xawt/libmawt.so

Backup the file first of course, just in case.

Re: [solved] Java AWT/Swing: a warning message

I just had this problem with trying to run jEdit. I found a solution elsewhere, but what peart said is pretty much the same, just in one line. I should have just searched these forums instead of Google. tongue
