[jira] [Commented] (QPID-3812) [Java] ExceptionListenerTest
sporadically fails on java-mms-0.10
[ https://issues.apache.org/jira/browse/QPID-3812?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13200538#comment-13200538 ]
Keith Wall commented on QPID-3812:
----------------------------------
This is a race condition. The Broker is sending the ConnectionOpenOk back to the client before it has updated its ConnectionRegistry. This leaves open the possibility that the ExceptionListenerTest can shut the broker down before the client's connection is registered internally, meaning that the Broker won't close the connection and the client won't get to report the exception to the client app.

It looks to me like problem is with ServerConnectionDelegate.java, line 172. The Broker should be updating its internal state before sending the ConnectionOpenOk.
