Subject [jira] Resolved: (HBASE-1327) NPE in HRegionServer$ToDoEntry.access$100
Date Thu, 05 Nov 2009 19:40:32 GMT

     [ https://issues.apache.org/jira/browse/HBASE-1327?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jean-Daniel Cryans resolved HBASE-1327.
---------------------------------------

    Resolution: Duplicate

Also this issue was filled on 0.19.1 when we were doing :

{code}
for (ToDoEntry e: this.toDo) {
  if (e.msg.isType(HMsg.Type.MSG_REGION_OPEN)) {
    addProcessingMessage(e.msg.getRegionInfo());
  }
} 
{code}

Now we check if the message is null. In both NPEs, this bug was already fixed so I'll mark
it as duplicate.
