Helen Williamson commented on ZOOKEEPER-1477:
---------------------------------------------
I'm also experiencing a similar problem using the zkCli shell script. I've
started up 5 zookeeper servers using QuorumPeerMain from the zookeeper jar.
With Java 1.6.0_37 I get the following output:

This can be reproduced by switching JAVA_HOME between 1.6 and 1.7.

> Affects Versions: 3.4.3
> Environment: Mac OS X Lion (10.7.4)

> Java(TM) SE Runtime Environment (build 1.7.0_04-b21)
