---------------------------------------------------------------------
I am not sure that I follow you. Your initial comment was about the fact that
we do not have testing support for Linux-aarch64 and your new comment is about
the fact that the testing is not good enough.
If your problem is about 2.2. I will not argue about that and revert my commit
in that branch.

> Analyze:
> This issue is caused by bundled jna-4.0.0.jar which doesn't come with aarch64
> native support. Replace lib/jna-4.0.0.jar with jna-4.2.0.jar from
> http://central.maven.org/maven2/net/java/dev/jna/jna/4.2.0/ can fix this
> problem.
> Attached is the binary compatibility report of jna.jar between 4.0 and 4.2.
> The result is good (97.4%). So is there possibility to upgrade jna to 4.2.0
> in upstream? Should there be any kind of tests to execute, please kindly
> point me. Thanks a lot.
