> While a message is being retransmitted from a client (RM-Source) from its retransmission
queue, the corresponding message might be acknowledged and its resource released at the client.
And in this case, an NPE will be thrown during the resending of the message.

The issue itself does not break the delivery guarantee semantics as the resend is failing
because the message has been acknowledged.
