Hi Magnus, I recently limited the amount of data that is returned via JMX/management, with a default of 256 bytes[1]. For large messages, the body should be a string "large message", ensuring that just to browse large messages does not require us to load the message body into memory on the broker or pull in the large message file.
I don't think it is reasonable to expect to be able to view the contents of a large message via the console but I would expect the view to be consistent. If 2.18.0 is not consistent we can resolve that, please raise an issue to track.
