JSN security test headline/noWarningApp failed with NPE exception, but it can PASS with JDK 7.0 promoted b24. It should be a regression.

N/A

I have not tried to run the test, but from the code it looks like a regression from fix 6608764
(PropertyChangeListeners machinery should have a better locking scheme).  The fix has introduced
new transient field changeSupportLock, but this field is not initiallized in readObject().
