   JCK tests may fail with JIT's spurious NullPointerExceptions.
  
   The statistics says at least one of JCK Swing tests fails
 with such NPE in slave JVM in master-slave run. The example of
 NPE stack trace you may see below. Moreover, this JIT NPE failure
 depends on:

1.The cpu load of the station where tests are executing.
   The high load reduces possibility of failure, for example:
    a) "-trace" option for Slave
    b) or "trace" option of JIT (JIT_ARGS)
       It maybe not reproducible at all in this case.
       
2. How many tests have been executed in the JVM of MasterSlave before.

   It shows some "accumulated" reason of this bug.
   The set of JCK swing tests is enough for reproduce at least one
   failure.
   
3. The speed to access class-files.
    The access for class-files located on fast local filesystem reduce
    possibility of the failure.
    
4. The failure becomes reproducible in this run, i.e
   repeating of the test causes the same failure.
   
   
   Failed on Solaris 2.5.1 w/o patch.
   Not reproducible under Solaris 2.6
   Not tested under patched Solaris 2.6
 
   Unfortunatelly the minimal test extends to 411 sub-tests invokations
   that is not easier than JCK swing run in same Slave JVM.
