Info regarding the MacOS JProgressBar bug

[Eirik Bakke]

Another Aqua JProgressBar-related crash (livelock?): Today my Java app
stopped responding with 100% CPU utilization; the attached VisualVM thread
dump shows the event dispatch thread stuck in the native method
apple.laf.JRSUIControl.paintImage, called via
com.apple.laf.AquaProgressBarUI.paint(AquaProgressBarUI.java:164).

This crash happened while doing a tab pane drag-and-drop operation in a
NetBeans Platform-based window system to relocate a sidebar in the window
layout. In this case the NetBeans window system does an offscreen paint of
the dragged panel (which contained a JProgressBar); this may have confused
the painting code. I was able to reproduce this crash several times,
getting the same stack trace in the event dispatch thread every time.
