Ubuntu Jaunty unusable for Swing debugging ?

I (and Thomas Singer) am having trouble with debugging Swing GUIs under Jaunty. The problem, described in this post doesn’t seem to be only related to IDEA, but is rather annoying : the whole desktop freezes when the debugger reaches a breakpoint. The only way to release the lock is to switch to a console with CTRL+ALT+F1 and kill the debugged process.

It looks like some already had the problem with Netbeans in previous versions of the JDK, and a workaround was available thanks to the AllowDeactivateGrabs option in xorg.conf. However, it seems that this option has been removed from Xorg. That’s a pity as it just doesn’t leave any workaround for this bug.

If anyone has a solution, please do not hesitate to comment this post, or join the discussion
