Timothy Bish commented on ARTEMIS-955:
--------------------------------------
[~harrison-tarr] No you aren't doing anything wrong, it's a bug on the broker
side that's affecting you.
> Artemis does not handle message with an integer as the body on topics
> ---------------------------------------------------------------------
>
> Key: ARTEMIS-955
> URL: https://issues.apache.org/jira/browse/ARTEMIS-955
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Components: AMQP
> Affects Versions: 1.5.1, 1.5.x
> Reporter: Harrison Tarr
> Priority: Minor
>
> When sending a message that contains only an integer as the body to a topic
> with multiple subscribers, the messages fail to be consumed.
> I have written some code that can replicate the problem. It is based off of
> the `activemq-artemis` topic example. It can be found at
> https://github.com/apache/activemq-artemis/compare/master...harrison-tarr:artemis-integer-message.
> To toggle "working" and "failing" behavior back and forth, there is a block
> of code at lines 83/84 and 88/89. If the comments on those blocks are
> switched, artemis will exhibit working behavior.
> The exception seems to be:
> ```server-out:13:47:32,611 WARN
