Subscribes and returns a Flow of messages of type T that unsubscribes automatically when the collector is done or cancelled. The returned flow can be collected only once.
The received MESSAGE frames are converted to instances of T or null, but the exact conversion is implementation-dependent. Message frames without a body MAY be skipped or result in an exception depending on the implementation, they don't have to be translated into null values. Conversely, message frames with a non-empty body may result in null values in the flow depending on the implementation.
See the general StompSession documentation for more details about subscription flows and receipts.
