Reason for closing:  Won't fix
Additional comments about closing:  This can't be fixed for netbeans only.
Must have been fixed (java-)system-wide.

Just rebuild the netbeans package against Testing

Try this as root:
sed -i 's/XINERAMA/FAKEEXTN/g' /opt/java/jre/lib/amd64/xawt/

The i686 users should use:
sed -i 's/XINERAMA/FAKEEXTN/g' /opt/java/jre/lib/i386/xawt/

thank you, Victor. I just want to add that this is not an netbeans error. It appears when starting almost any java application.

This problem still exists with jre-6u5-1.
Comment by Timm (gummibaerchen) - Friday, 04 April 2008, 14:16 GMT
Yeah, sadly.

But the bug should not be filed against netbeans, 'cause I can't do anything about it.
It jre related..

any idea why jre is behaving like this? Even a simple

String s = javax.swing.JOptionPane.showInputDialog( "Please enter String" );

causes this.

I also see the locking message when running a source tarball version of frostwire.
