[ https://svn.apache.org/r1673014 ]
QPID-5818 : [Java Broker] creating children from within the configuration
thread leads to deadlock as the configuration thread blocks waiting for a task
which cannot be executed because it needs the config thread. Instead use
asynchronous child creation.
> AMQP model mutating actions should use task executors

> Key: QPID-5818
> URL: https://issues.apache.org/jira/browse/QPID-5818
> Project: Qpid
> Issue Type: Improvement
> Components: Java Broker
> Reporter: Keith Wall
> Fix For: 6.0 [Java]
>
>
> All AMQP actions (queue declare etc) that mutate the model must use the task
> executor in order to fit with the scheme whereby all model updates are the
> responsibility of a single thread.
> There are a couple of interesting corner cases:
> Queue browsers - consuming the last message causes the consumer to close
> (=model operation)
> Sending message that cannot be routed cause the connection to be closed
> (=model operation).
> Scope must include AMQP 0-8, 0-10, 1-10 and management interfaces.
