Description swpalmer 2008-01-08 19:21:10 UTC
Running NB 6 on Windows XP SP2, JDK 1.6.0_03

After unlocking my workstation sometimes the Netbeans application is locked up and will not paint anything.

Will attach a thread dump.

Possibly related to issue #124524
Comment 3 David Simonek 2008-01-09 08:14:45 UTC
I see nothing special in attached thread dump, no dead lock in our code or anything similar. System seems to be just
painting the content at the time thread dump was obtained. Hardly we can do anything here...

Does it happen with other JDK versions as well?
Does it happen with other Java apps (like SwingSet2 demo in jdk demos)?
What is the best way to reproduce the problem?
Comment 4 swpalmer 2008-01-11 01:50:27 UTC
I suspect that the number of windows on the screen might have an effect.  Perhaps relating to available memory on the
graphics card.  This could be a JRE issue relating to the loss of accelerated surfaces or the Swing back buffer.  I
suspect it may be related to the "gray rect fix" in the JRE, though I have only noticed it with Netbeans so far.  It
doesn't happen often.  I've only seen it twice as far as I can recall.  In this state the entire content area of the
netbeans window is solid white.  Iconifying the window and restoring it has no effect. Dragging other windows over it
and exposing new regions has no effect.

Hmm, that's not enough for us to find or even fix the bug. I'm closing, please feel free to reopen with some more
reproduction hints when error appears again, thanks.
