[jira] [Updated] (QPID-6619) NPEs when creating consumers / queues
[ https://issues.apache.org/jira/browse/QPID-6619?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Keith Wall updated QPID-6619:
-----------------------------
Description:
http://qpid.2158936.n2.nabble.com/NPEs-when-creating-consumers-queues-td7627389.html
I am testing using Java broker 0.32 with client 0.16, and have run into
NPEs when I create consumers to queues in an initialization step to force
the queues to be created. I'm not able to reproduce this reliably, and it's
possible that this is triggered by some race condition, since we can have
multiple threads trying to register consumers to these new queues at the
same time. Any idea what is causing this? (We used to use the 0.16 broker
with the same initialization and didn't run into this.)
Stacktrace I've seen:
