Trivial Description
An AMQP Connection that is opened by a remote peer requires that the broker also send an open frame prior to sending any close frame with an error condition set to indicate failure. This can lead to the remote peer appearing to be open for a short while before receiving the follow on close frame. In order to make it know to a client that its open request has actually failed the connection property "amqp:connection-establishment-failed" as a hint that a close frame follows.
