[jira] [Commented] (ZOOKEEPER-1477) Test failures with Java 7 on
Mac OS X
[ https://issues.apache.org/jira/browse/ZOOKEEPER-1477?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13463222#comment-13463222 ]
Diwaker Gupta commented on ZOOKEEPER-1477:
------------------------------------------
Update:
* With JDK 7u7 on Mac and ZK 3.4.3, I don't see the ConnectionLoss exceptions anymore (rather I haven't yet observed them)
* With JDK 7u7 on Mac and ZK 3.4.4, I see even more ConnectionLoss exceptions than before :-/

> 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.
