--------------------------------------
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.

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.
