Summary: ClassCastException rendering Tasks window on Windows L&F
Initial Comment:
When running on Windows (7 & Vista), i.e. when the Window Look & Feel is used,
the following exception occurs when the Tasks progress window is displayed:
Exception in thread "AWT-EventQueue-0" java.lang.ClassCastException:
javax.swing.plaf.ColorUIResource cannot be cast to java.util.List
(full stack-trace below)
This causes problems displaying the Task window (and other windows), see the
attached screen shot.
Googling suggests this exception occurs when windows are rendered on a thread
other than the Event Dispatch Thread (see SwingUtilities.invokeLater())
