> Key: QPID-6469
> URL: https://issues.apache.org/jira/browse/QPID-6469
> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Affects Versions: 0.18, 0.19, 0.20, 0.21, 0.22, 0.23, 0.24, 0.25, 0.26, 0.27, 0.28, 0.29, 0.30, 0.32
> Reporter: Alex Rudyy
> Assignee: Alex Rudyy
>
> If an exception occurs whilst processing AMQProtocolEngine#exception this is caught by the uncaught exception handler and this causes the Broker to exit. Failures to close the connection should be logged and ignored.
> This stacktrace below demonstrates the issue. It is possible in this case transaction timeout had cause the connection closed at the same point that the client tried to perform a command.
