Bhallamudi Venkata Siva Kamesh commented on ZOOKEEPER-1059:
-----------------------------------------------------------
When stat command is issued with a path,zookeeper returns the stat of node of
the given path.If no such node exists returns null.
{code:title=ZooKeeperMain.java|borderStyle=solid}
stat = zk.exists(path, watch); // Returns null when No node exists of given path
printStat(stat); // When stat is null, this method throws NPE
{code}
> stat command isses on non-existing node causes NPE
