--------------------------------
I applied the fix of this PR online and saw that the frequency of full gc was
greatly reduced, but still occurred after a long running time. It was also
difficult for me to simulate the abnormal sending behavior of the client. Do
you have any findings and suggestions? [~showuon]

> When the client sends a produce request in an abnormal way and the server
> accepts it for deserialization, a "java.lang.IllegalArgumentException" may
> occur, which will cause a large number of "TopicProduceData" objects to be
> instantiated without being cleaned up. In the end, the entire service of
> kafka is OOM.
