I wholeheartedly support this idea in theory. But it seems scary in 
practice. We would need to run all automatic and manual AWT regression 
tests on at least all major WMs (Metacity, Kwin, Compiz, and (sic!) CDE 
- as long as we support Solaris CDE desktops, not sure if this is 
relevant to JDK 8 though) to ensure no regressions arise. Note that we 
have to test this with quite old versions of the WMs, e.g. Metacity from 
Gnome 2.6 (or is it 2.4?) - this is what Solaris 10 has to offer, etc. 
And ideally we would also want to test on all those forgotten/rare 
creatures like SawFish, Motif, Enlightenment, etc. This looks like a lot 
of work for such a simple fix.

However, your current fix looks pretty safe and is fully consistent with 
our current XAWT code.

Artem, what's your opinion?
