[jira] [Created] (ARTEMIS-1601) NPE silently thrown in StompSession#sendMessage

Johan Stenberg created ARTEMIS-1601:
---------------------------------------

             Summary: NPE silently thrown in StompSession#sendMessage
                 Key: ARTEMIS-1601
                 URL: https://issues.apache.org/jira/browse/ARTEMIS-1601
             Project: ActiveMQ Artemis
          Issue Type: Bug
          Components: STOMP
    Affects Versions: 2.4.0
         Environment: Artemis 2.5.0-SNAPSHOT
            Reporter: Johan Stenberg
            Assignee: Justin Bertram


During debugging a stomp session I realized that the StompSession's send method does not check if looking up a subscription returns null:
{code:java}
StompSubscription subscription = subscriptions.get(consumer.getID());
{code}

This later sometimes results NPEs at:
{code:java}
if (subscription.getAck().equals(Stomp.Headers.Subscribe.AckModeValues.AUTO)) {
{code}
