[jbosscache-issues] [JBoss JIRA] Updated: (JBCACHE-1587) Avoid NullPointerException in CreateNodeCommand.rollback()

[Takayoshi Kimura (JIRA)]

     [ https://jira.jboss.org/browse/JBCACHE-1587?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

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

    Description: 
Under load the CreateNodeCommand.rollback() could fail with NullPointerException when parent node is not found. This exception itself is harmless but it would be better to convert NPE to other exception like CacheException. 

2010-07-26 14:48:21,683 WARN  [org.jboss.cache.interceptors.TxInterceptor] (Incoming-6,192.168.1.23:43834) Rollback had a problem	
java.lang.NullPointerException	
	at org.jboss.cache.DataContainerImpl.removeLegacy(DataContainerImpl.java:651)
