Diwaker Gupta commented on ZOOKEEPER-1477:
------------------------------------------

[~mahadev] Happy to test though I'm pretty sure this is unrelated to 
ZOOKEEPER-1550 -- recall that I'm using Oracle JDK (not OpenJDK) and I'm on 
Mac. I haven't been able to ever successfully run ZK tests on a Mac with JDK7 
(starting with 7u3, now on 7u7). Things were broken with ZK 3.4.3 and have just 
become worse with 3.4.4. Will report back shortly with the patch in 1550.

> As background, I was actually investigating some non-deterministic failures 
> when using Netflix's Curator with Java 7 (see 
> https://github.com/Netflix/curator/issues/79). After a while, I figured I 
> should establish a clean ZK baseline first and realized it is actually a ZK 
> issue, not a Curator issue.
> We are trying to migrate to Java 7 but this is a blocking issue for us right 
> now.
