, I not only added this pr processing when I fixed it myself, but also
performed a set-null operation on this leaked collection.

> 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.
