JCK : JCK1.5a
J2SE : 1.5 (build 1.5.0_04-b05, mixed mode, sharing)
Platform[s] : Linux
JCK test owners: http://javaweb.sfbay/jcce/tcks/jck/docs/others/owners.jto
switch/Mode : FAILED with -Xshare:on on x86 machine with Hyper-Threading support
                 PASSED with -Xshare:on on x86 machine WITHOUT Hyper-Threading support

Failing Tests :
==================
api/javax_swing/JColorChooser/index.html#getsetTests


JCK test source location:
==========================
/java/re/jck/1.5a/latest/binaries/JCK-runtime-15a/tests


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.
