------------------------------------
Assignee: (was: Martin Ritchie)
> Client can fail to notify all stateWaiters
> ------------------------------------------
>
> Key: QPID-1432
> URL: https://issues.apache.org/jira/browse/QPID-1432
> Project: Qpid
> Issue Type: Bug
> Components: Java Client
> Affects Versions: M2.1, M3
> Reporter: Martin Ritchie
> Priority: Critical
> Fix For: M4
>
>
> Summary:
> Due to our desire to reduce synchronization on the client it is possible to
> fail to notify a client of an exception state.
> As highlighted by the two thread processes below, the _waiters in
> AMQStateManger can be updated such that the error notification fails to take
> place.
> This is due to our use of CopyOnWrite lists. As the Exception handler is
> propagating the exception a new exception may miss a newly registered state
> listener.
> Suggested change:
> All uses of the _waiters should be synchronized. The only place that this is
> not done is in the error() case.
