[Bug 1241101] Re: Java crash in libglib-2.0 after upgrade from 13.04 to 13.10

[Quinn Balazs]

I've taken a look at this, and seemingly randomly*, java frames flipflop
between what we've seen here, and the

j  org.eclipse.swt.internal.gtk.OS._g_object_get_qdata(JI)J+0
j  org.eclipse.swt.internal.gtk.OS.g_object_get_qdata(JI)J+9
j  org.eclipse.swt.widgets.Display.removeWidget(J)Lorg/eclipse/swt/widgets/Widget;+19
j  org.eclipse.swt.widgets.Combo.deregister()V+21
j  org.eclipse.swt.widgets.Widget.releaseWidget()V+1

that we've seen in bug #1205452. Changing GTK2 appearance will on
occasion clear up the issue, but works nowhere near 100% of the time.
Once I've done a bit more digging and am sure that these issues are at
their roots the same, bug #1205452 can be marked as a duplicate of this
issue, and maybe a bug pattern can be written for this issue (23
affected in #1205452, 16 affected here, and most people using Eclipse or
a derived product will run into this issue)

*Nothing is random, I'm working on associating these differences to user
actions.

  I tried different version of Java (Oracle v7 and v6 jre) with same
  result. Also, Eclipse display blank menus so there's a general java
  problem with displays.
