[jira] [Commented] (ZOOKEEPER-1477) Test failures with Java 7

["Patrick Hunt (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ZOOKEEPER-1477?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13288958#comment-13288958 ] 

Patrick Hunt commented on ZOOKEEPER-1477:
-----------------------------------------

ZK runs pretty cleanly against java7 on Apache jenkins:
https://builds.apache.org//view/S-Z/view/ZooKeeper/job/ZooKeeper-trunk-jdk7/

What's different about your environment? Perhaps you don't have sufficient resources to run (e.g. overloaded system? over virtualized, etc...)

> 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.
