@mo-beck This PR should not be associated with any JBS issues which are targeted at repo-aarch64-port. All such issues
should have been closed by now when the associated code was pushed to aarch64-port repo. That was the whole point of
creating separate issues so that they could be tracked in the porting repo. Now that all of that work should be
complete the only issue that should remain open in relation to the Windows-Aarch64 port is JDK-8248238. Thanks.
