There have been some problems in the past with assumptions that Java Windowing
toolkits makes about window manager behaviour which XWin's multiwidow mode
breaks (e.g. [1],[2]), so this might be something similar.

If you can provide a *small* Java application which demonstrates the problem,
and the precise java version which you are using, I will see if I can
reproduce and investigate the problem.
