----------------------------------------
Summary: Test failures with Java 7
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: Critical
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.
