Note that the "Second destination failed to receive message" is an indication
of the problem - the connection is blocked. However, the "FAILED to hit
producer-flow-control at 1000" error means the test case didn't work as
expected because PFC was expected to block sends and didn't appear to do so.
> Client / NetworkBridge Connection blocks all communication at the transport
> when producer-flow-control reached

> Key: AMQ-3875
> URL: https://issues.apache.org/jira/browse/AMQ-3875
> Project: ActiveMQ
> Issue Type: Bug
> Affects Versions: 5.4.2
> Reporter: Arthur Naseef
> Attachments: TestProducerFlowControl.java,
> TestProducerFlowControl.java
>
>
> When producer-flow-control throttles a producer, the entire connection for
> the client, or network bridge, can be blocked until space clears.
> A unit test will be attached that demonstrates this situation with any of the
> following types of messaging:
> * PERSISTENT, transacted
> * NON-PERSISTENT, non-transacted
> * NON-PERSISTENT, transacted
> PERSISTENT, non-transacted messages don't have this problem. Internally, it
> seems that any time messages are sent asynchronously across the transport
> (i.e. isResponseRequired() == false), the problem occurs.
> The expected operation is for producers to the destination to block on send()
> and all other operations across the same connection to continue normally.
