[jira] [Resolved] (QPIDIT-82) JMS tests fail intermittently with null message

["Kim van der Riet (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/QPIDIT-82?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Kim van der Riet resolved QPIDIT-82.
------------------------------------
    Resolution: Fixed

The cause of this error is insufficient timeout while the receiver is waiting for a message. As both the sender and receiver are started on separate threads in their own JVM, it takes a second or so for each JVM to start. As the timeout was set to a value of 1000 (ms) and the receiver is started first, followed by the sender, a few tests were failing because the receiver was timing out waiting for the sender to start.

This problem was solved by increasing the timeout value from 1000 (ms) to 10000 (ms). The 1 second value would have been reasonable if the JVMs were all already started or if the producer and consumer were sharing a JVM.

In addition, adding a proper exception to the timeout would allow messages which are not received because of a timeout to show a meaningful exception:
{noformat}
AssertionError: Caught exception, exiting.
java.lang.Exception: Receiver::run(): No message, timeout while waiting
