The Java2D demo utilizes a tabbedPane within a tabbedPane. The inner tabbbedPane doesn't refresh entirely to the current tab under a specific condition. Follow the steps to reproduce to see the symptoms.

Build :
The next promoted build "I" or /net/capra/export/JavaMedia/2D/builds/current/solaris

Demo location :
demo/jfc/Java2D

Steps :
  1. launch demo with : % java Java2Demo
  2. In Arcs_Curves tab single click in the Arcs demo canvas.
  3. Select the Arcs_Curves.Ellipses tab (inner tabbedPane)
  4. Select the Arcs_Curves.Arcs tab (inner tabbedPane)
  5. Select the Clipping tab (outer tabbedPane)
  6. Select the Arcs_Curves tab (outer tabbedPane)

Symptoms :
The Arcs_Curves.Arcs tab is the selected tab and animation is happening (See Performance monitor). But the black background from the Arcs_Curves.Ellipses covers the Arcs_Curves.Arcs selected component.

I've tried invalidates, validates and repaints to no avail.
