A DESCRIPTION OF THE PROBLEM :
There is a problem with JColorChooser that can cause the entire application to freeze permanently.

This happens when we open the JColorChooser multiple times and it can also reproduced with the attached code. Sometimes the test code freezes after 30 iterations, sometimes after 250 or 2000 iterations.


Try to set Look&Feel to javax.swing.plaf.metal.MetalLookAndFeel
