A DESCRIPTION OF THE PROBLEM :
Swing does not recursively enable or disable complex components.  Because of this, a complex control like the JColorChooser does not disable its sub-components, and the developer must do this if he desires to disable the chooser.

When writing code that does this to a JColorChooser, the sample shows that there is an exception in an image loading thread and this causes the Event Dispatch Thread to hang on a MediaTracker.wait().



STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Compile and run the attached source code.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I would expect the JColorChooser to appear in the dialog with all the subcomponents disabled.
ACTUAL -
The AWT window stops repainting, and an exception appears on stderr.


ERROR MESSAGES/STACK TRACES THAT OCCUR :
Exception in thread "SyntheticImageGenerator" java.lang.NullPointerException
	at java.awt.image.ImageFilter.setProperties(ImageFilter.java:90)
	at javax.swing.colorchooser.SyntheticImageGenerator.run(SyntheticImage.java:111)


REPRODUCIBILITY :
This bug can be reproduced always.
