> In our environment we use an embedded broker. On one topic where compression is enabled,
the server is also listening in on the messages. From ActiveMQ 5.10.0 up to 5.13.0, we encounter
DataFormatException: incorrect header check exceptions on the tcp clients due to corruption
of the payload. Attached are a test server and client. At some point, the client will exit
due to mentioned exception. Increase chances by running multiple clients. This scenario works
with 5.8.0 and 5.9.1.
> If the server has multiple consumers on the same topic, they will encounter corruption
as well, but this has other side-effects.
