HonglunChen commented on CURATOR-540:
-------------------------------------

[~cammckenzie], like Jordan's advice,  I call 
CuratorFramework.blockUntilConnected() before starting PathChildrenCache to 
avoid this. I met this issue after upgrading curator 2.7 to 2.13, I thought it 
was a bug.  But on the other hand, as join says, it's probably not a bug. Now 
I'm not sure it needs fixing.

> I debugged and found the root cause : In PathChildrenCache, CONNECTED state 
> is triggered before currentData initializes.
