StompDecoder Logs Null Session IDs for Heartbeats [SPR-15937]

[spring-projects-issues]

Steve Roy opened SPR-15937 and commented

When enabling the TRACE log level on the StompDecoder, a null session id is logged for heartbeats in the Spring WebSocket STOMP client.

Here is a logging sample:

11:39:03 [WebSocketClient-AsyncIO-1] StompDecoder - Decoded heart-beat in session null
11:39:30 [WebSocketClient-AsyncIO-1] StompDecoder - Decoded heart-beat in session null
11:39:31 [WebSocketClient-AsyncIO-1] StompDecoder - Decoded heart-beat in session null
11:39:32 [WebSocketClient-AsyncIO-1] StompDecoder - Decoded heart-beat in session null
11:39:36 [WebSocketClient-AsyncIO-1] StompDecoder - Decoded heart-beat in session null

Why was the ticket closed?

Ah sorry, I meant to add that we're not logging "with session null" now anymore but rather just "Decoded heart-beat" in such a case.
Or are you rather wondering about heart-beats without a session in the first place?

In any case, the commit isn't pushed yet. Coming along with a few others later today.

ok - I didn't see the commit so I was wondering what the status was.

Yes, the pending commit addresses the concern.

While developing / debugging it raises questions to see a null session id in the log statements. It looks like having the session id available to that location in the code would require some design / code re-organization for a minor issue. Just removing the session id from the log statement helps for now - thank you.
