[Java Broker] [WebSocket] Websocket implementation must not assume that web socket frame contains a whole AMQP frame

      Description

      Currently the Java Broker's AMQP web socket implementation does not uphold all the following:

      Advanced Message Queuing Protocol (AMQP) WebSocket Binding (WSB) Version 1.0 Committee Specification 01 2.4 Exchanging AMQP Frames

      There is no mapping between an AMQP frame and a WebSocket message. Therefore, a single AMQP frame MAY be split over one or more consecutive WebSocket messages. Conversely, a single WebSocket message MAY contain one or more AMQP frames. There is also no mapping between an AMQP frame and a WebSocket frame. Therefore, a single AMQP frame MAY be split over one or more consecutive WebSocket frames. Conversely, a single WebSocket frame MAY contain one or more AMQP frames.

      The current implementation will fail if a websocket frame arrives containing a partial AMQP frame. Furthermore since, QPID-7763, internally WebSocketProvider chunks the incoming bytes into QBBs. If this chunking results in a frame overlapping a chunk boundary, processing will fail.
