------------------------------------------
I noted this in javac's output when using Oracle Java 7 on Linux:

> Key: ZOOKEEPER-1477
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1477
> Project: ZooKeeper
> Issue Type: Bug
> Components: server, tests
> Affects Versions: 3.4.3
> Environment: Mac OS X Lion (10.7.4)
> Java version:
> java version "1.7.0_04"
> Java(TM) SE Runtime Environment (build 1.7.0_04-b21)
> Java HotSpot(TM) 64-Bit Server VM (build 23.0-b21, mixed mode)
> Reporter: Diwaker Gupta
> Priority: Blocker
> Fix For: 3.4.5
>
>
> I downloaded ZK 3.4.3 sources and ran {{ant test}}. Many of the tests failed,
> including ZooKeeperTest. A common symptom was spurious
> {{ConnectionLossException}}:

> 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.
