------------------------------------
Summary: [Java broker] ensure the IoSender is stopped when a
connection closes before recieving a protocol initiation
Key: QPID-4489
URL: https://issues.apache.org/jira/browse/QPID-4489
Project: Qpid
Issue Type: Bug
Components: Java Broker
Affects Versions: 0.18, 0.17, 0.16, 0.15, 0.14, 0.19, 0.20
Reporter: Robbie Gemmell
Fix For: 0.21
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 if its closed() method is called.
