Shevek updated CURATOR-10:
--------------------------
Attachment: ByteCodeRewrite-ZooKeeper-3.5.x.patch
Apache hates my whitespace conventions, but here's a working patch. Mangle to
taste.
> NPE from JMX infrastructure in curator-test
> -------------------------------------------
>
> Key: CURATOR-10
> URL: https://issues.apache.org/jira/browse/CURATOR-10
> Project: Apache Curator
> Issue Type: Bug
> Reporter: Shevek
> Assignee: Jordan Zimmerman
> Attachments: ByteCodeRewrite-ZooKeeper-3.5.x.patch
>
>
> QuorumPeer.java contains this:
> finally { MBeanRegistry.getInstance().unregisterAll(); }
> Since MBeanRegistry is static, this unregisters all MBeans from ALL
> QuorumPeers in a TestingCluster.
> This causes:
> [ERROR] NIOServerCnxnFactory - Thread
> Thread[QuorumPeer[myid=1]/0:0:0:0:0:0:0:0:41733,5,main] died
> <java.lang.AssertionError>java.lang.AssertionError
> at
> org.apache.zookeeper.jmx.MBeanRegistry.register(MBeanRegistry.java:89)
> at
> org.apache.zookeeper.server.quorum.FastLeaderElection.lookForLeader(FastLeaderElection.java:771)
> at
> org.apache.zookeeper.server.quorum.QuorumPeer.run(QuorumPeer.java:912)
> and similar when connecting a new client to a server after killing another in
> a test suite.
> Looking for a workaround, but bringing this to your attention early.
> Note: Code against ZK 3.5.x library, although that unregisterAll() call seems
> to predate that by a long way, so this is presumably valid throughout?
