Description
JCK : JCK-runtime-6b b24
J2SE : FAIL - jdk6u10 build 23, jdk 7 b26
Platform[s] : FAIL - All
switch/Mode : FAIL - any
Changes in java.awt.Component near line 635:
private transient final Object changeSupportLock = new Object();
private Object getChangeSupportLock() {
return changeSupportLock;
}
cause every call to synchronized (getChangeSupportLock()) for deserialized component to throw NPE, since changeSupportLock is transient and null for deserialized object.
Affected JCK 6b tests:
