--------------------------------------

             Summary: binary amqp message causes NPE when viewed in web console
                 Key: ARTEMIS-3550
                 URL: https://issues.apache.org/jira/browse/ARTEMIS-3550
             Project: ActiveMQ Artemis
          Issue Type: Bug
          Components: Web Console
    Affects Versions: 2.19.0
            Reporter: Erwin Dondorp


using an amqp message with just a byte array as body.

when viewed in the webconsole this results in a NullPointerException.

the code tries to comparing the contenttype header, which is absent here.

the resulting null-pointer is used, causing that NPE.

 

fixable by testing for a null-pointer in AMQPMessage.java(1904):
{code:java}
if (contentType != null && contentType.equals(AMQPMessageSupport.SERIALIZED_JAVA_OBJECT_CONTENT_TYPE)) {
{code}
 

note: 3 other occurrences of {{contentType.equals}} seem to be safe based on visual inspection.

 

the original stack trace:

I will add a PR to this issue as soon as I can, but feel free to beat me on that, as my "vanilla" development environment is a bit unusable at the moment.
