> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Affects Versions: 0.14, 0.15, 0.16, 0.17, 0.18, 0.19, 0.20
> Reporter: Robbie Gemmell

> If the IoReceiver exits (due to the TCP connection closing) before a protocol version initiation is received (successfully or otherwise), the IoSender will fail to be closed.
> In this case the IoReceiver signals closed() to the receiver it was created with, a MultiVersionProtocolEngine with an initial SelfDelegateProtocolEngine delegate, but this delegate fails to close the IoSender. The IoSender is currently only closed when a received version initiation fails and the broker replies with a valid protocol version (for negotiation purposes) before closing the network connection, or if the closed() signal occurs after a protocol version initiation succeeds and the MVPE delegate is replaced with the relevant versions delegate.
> The SelfDelegateProtocolEngine should be updated to close the associated network connection (and thus the IoSender) if its closed() method is called.
