Interesting.
In my experience (IntelliJ IDEA, soapUI) the problems while running
swing apps maximized where:

1. If I single-click a menu in the menu bar, the menu will flash
briefly and disappears (instead of staying opened).
2. If I click and hold on a menu in the menu bar, the menu stays
opened, but the selection is vertically displaced (I have to move the
mouse to the third menu item to select the first one, for example).
3. If I right-click to access a context-menu, the selection is
displaced as described in the previous case).

And a very minor annoyance: Gnome3 relies on the x-windows WM_CLASS
property to track applications instead of windows (see
http://live.gnome.org/GnomeShell/ApplicationBased).
Java swing apps, as far I can tell, don't set this property as gnome3
expects (which means the gnome3 keeps opening new instances of the app
every time I click the shortcut).

I'll submit the bug to openjdk and see how it goes.
