<AWT Dev> Patch for JTreg test java/awt/Mixing/LWPopupMenu.java

Hmmm... Thanks for providing the info.

On the second thought, I see that that isn't a problem in the test. AWT 
(and I presume, Swing) has many tests that work that way: display both a 
test frame and the dialog with the instructions/test output. Which means 
that hypothetically they all can fail. Do we want to add this toFront() 
call in the majority of our automated tests? I think the answer is negative.

What we observe here is an awkward behavior of a particular window 
manager - the Fluxbox. Note that XToolkit officially supports the 
Metacity window manager only (in 6, the CDE/dtwm is supported as well). 
Of course, sometimes we do indeed add some workarounds for rather 
popular window managers, e.g. for KDE, or Compiz. This, however, is not 
a general practice/requirement.

The list of officially supported window managers enables us to develop 
regression tests that pass when a fix works, and fail when it doesn't. 
And our tests are designed to work correctly on officially supported 
window managers only, because other WMs may bring some side-effects 
that, at least, should not be work-around'ed in the code of the tests 

So, this issue looks like an AWT bug, rather than a test problem. 
Moreover, that isn't even a bug, but an RFE to add better support for 
the Fluxbox in XToolkit.

best regards,
