-----------------------------------------
Summary: NullPointerException in AMQPMessage when browsing queue
with Artemis web console
Key: ARTEMIS-3717
URL: https://issues.apache.org/jira/browse/ARTEMIS-3717
Project: ActiveMQ Artemis
Issue Type: Bug
Components: AMQP
Affects Versions: 2.19.1
Reporter: Christian Danner

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 (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:
