> MockDatanodeStorage.writeChunk simply adds the bytestring chunk info into its
> internal map, and after HDDS-9843 which made chunk buffer direct buffer, it
> causes some sort of memory corruption as described in HDDS-10431. Suspect
> it's a JVM bug.
> Solution is simple: make a copy of the byte buffer.
> Thanks [~smeng] for narrowing down the culprit.
