["Christian Danner (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARTEMIS-3717?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17504262#comment-17504262 ] 

Christian Danner commented on ARTEMIS-3717:
-------------------------------------------

I also attached the patched class - it attempts to eliminate the possibility of NPE caused by toString() calls in general.

> Attached is a stack trace of a NullPointerException that happens when browsing a dead letter queue. It seems the NPE is caused by the following code in org.apache.activemq.artemis.protocol.amqp.broker.AMQPMessage (line 874):
> {{map.put(extraPropertiesPrefix + s.toString(), JsonUtil.truncate(o.toString(), valueSizeLimit));}}
> because the property value can obviously be null. Applying a patch that calls String.valueOf(o) instead fixes the NPE and it can be seen that the problem is caused by the AMQ_ORIG_QUEUE property whose value is null:
