Takayoshi Kimura updated JBCACHE-1587:
--------------------------------------

                       Summary: Avoid NullPointerException in CreateNodeCommand.rollback()  (was: Avoid NullPointer)
             Affects Version/s: 3.2.2.GA
                   Description: 
Under load the CreateNodeCommand.rollback() could fail with NullPointerException. This exception itself is harmless but it would be better to convert NPE to other exception like CacheException.
