Problem description:
=====================
The following JCK1.5a tests:
  api/javax_swing/JColorChooser/index.html#getsetTests
hangs when running in a loop.

The problem can be reproduced with running it in a loop. Below is the exact command line:

while `true` ; \
  do $JDK_HOME/bin/java -Xverify:all -Xshare:on \
  -cp $JCK_HOME/JCK-runtime-15a/classes -Djava.security.policy=$JCK_HOME/JCK-runtime-15a/lib/jck.policy \
  javasoft.sqe.tests.api.javax.swing.JColorChooser.getsetTests -TestCaseID ALL; \
done


It is known that the loop eventually hangs on Linux machine with Hyper-Threading processors
when java is run with -Xshare:on option. The loop does not hang on Linux machines without
Hyper-Threading processors.

N/A

Talked to   xxxxx@xxxxx  . Since all we really have here is a hanging MediaTracker, makes sense to have 2D look at this first.
Posted Date : 2006-04-24 16:53:34.0

According to thread dump from the bug description, the SynteticImageGenerator
thread waits on isDirty flag when  first row of HSBImage is calculated
(DefaultHSBChooserPanel.java, lines 720 - 722).

However, if method addConsumer() (DefaultHSBChooserPanel.java,
lines 646 - 649) is called after the start of image production
(i.e, atert the start of the SynteticImageGenerator thread),
the wait() on line 721 never get notification about isDirty changes.
In this case, the image is not produced and MediaTracker never gets
first image frame.

It looks like this scenario happened when JCK test was ran on smp linux
system with -Xshare:on flag.

To solve this problem, we can call notifyAll() after isDirty
flag changes like it is done in the nextFrame() method of the
HSBImage class.

The problem is in the SyntheticImage class that is used to draw the color diagram.
This class was rewritten in the fix for the 6552812 bug.

It is fixed in JDK 7.
It is marked as a duplicate because it is fixed during the ColorChooser refactoring.
