Keith Wall resolved QPID-6974.
------------------------------
Resolution: Cannot Reproduce
On closer inspection, it appears that locking in the code does not allow this
to happen. The root cause of this AMQFDE remains unexplained.
> Timeouts occurring within IoSender may result in an illegal AMQP stream being
> sent to the peer

> Key: QPID-6974
> URL: https://issues.apache.org/jira/browse/QPID-6974
> Project: Qpid
> Issue Type: Bug
> Components: Java Broker, Java Client
> Affects Versions: 0.32, qpid-java-6.0
> Reporter: Keith Wall
>
> This defect applies to the legacy Java Client only for 6.0.0, and to both the
> Java Broker and Java Client for <= 0.32.
> If the IoSender is in use by multiple threads, as might be the case if a
> client application were using multiple JMS Sessions on a single Conection,
> there is the possibility that if a #send() call times out, another thread
> might succeed in it #send call, if there is space becomes available in the
> buffer. This could result in in a corrupt AMQP stream being received by the
> peer. The first caller's buffer will be partially sent and then followed by
> second callers.
> This would lead to same symptom as report in QPID-6206. The following stack
> trace was generated by a 0.32 derivative.
