> Key: QPID-7582
> URL: https://issues.apache.org/jira/browse/QPID-7582
> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Reporter: Keith Wall

> As highlighted by a NPE from TxnCoordinatorReceivingLink_1_0#discharge:151, the AMQP 1.0 protocol layer assumes that {{Discharge#fail}} is never returns null. The code un-autoboxes the object back to its primitive. The spec allows it to be, so a NPE will results in this situation.
> We need to check all the implementation classes that back AMQP performative. For any field marked as optional which is of a type subject to auto-box, defensive code must be added.
