@brusdev , what problem are you trying to solve here?

[brusdev]

@ggallen a Jenkins job is able to get the message headers and content using the trigger[1] but not using the waitForCIMessage step. Feel free to close this PR if it doesn't make sense.

But @brusdev , the headers/properties are added in https://github.com/jenkinsci/jms-messaging-plugin/blob/jms-messaging-1.1.24/plugin/src/main/java/com/redhat/jenkins/plugins/ci/messaging/ActiveMqMessagingWorker.java#L272-L279.

I think what @brusdev is trying to get across is the fact that

jms-messaging-plugin/plugin/src/main/java/com/redhat/jenkins/plugins/ci/messaging/ActiveMqMessagingWorker.java

Line 525 in 50cd443

String value = getMessageBody(message);

only returns the message body and NOT the message headers.
