session closed: 0, reason: The decoded text message was too big for the output buffer and the endpoint does not support partial messages about java-slack-sdk HOT 6 CLOSED

I realized that calling RTMClient#disconnect() then RTMClient#connect()surely doesn;t work for the case. So, since version 1.3.0, I've added RTMClient#reconnect() which works for any cases.

Also, I applied the changes to RTMClient regarding its behavior when receiving some errors. Previously, the client used to abandon the underlying WebSocket session when it gets errors, anyway. But I found that it's not a proper way to handle errors. Therefore, since version 1.3.0, the default error handler no longer does the removal of sessions. The change may be beneficial for your use cases.

I've not investigated your situation on my end yet but, at least, I can say that you don't need to reboot the entire application. RTMClient doesn't depend on any states inside your singleton Slack instance except for wssUrl. So, I guess, when you have the unexpected shut down of the RTM client, you should be able to recover it by just calling RTMClient#disconnect() then RTMClient#connect(). The connect method establishes a new session with the server. https://github.com/seratch/jslack/blob/1.1.7/src/main/java/com/github/seratch/jslack/api/rtm/RTMClient.java#L31-L35

Weirdly, that did not work.
I stopped making Slack a bean and instead created a holder that was a bean, had it discard and recreate the Slack object and initialize it.
That works, and for now, my problem is gone.

I'll leave this open to investigate the The decoded text message was too big for the output buffer and the endpoint does not support partial messages error.

Thanks!
