--------------------------------
Description:
The following issue is caused by deprecated buffer cleaner on higher version of
JDK11, it needs to be investigated and refactor the code logic according to new
method for native memory backed bytebuffer cleaning.
{code:java}

Reclaim Memory Buffer: 759EBB3D Size: 1329017
Exception in thread "main" java.lang.IllegalArgumentException: object is not an
