Apparently clang believe this is an error, and not just a warning, so 
this is a source code issue, and not a build issue per se.

If this only happens in panama, you need to raise it with the Panama 
developers (cc:ed). If you can also reproduce it on the main jdk/jdk 
repo, then you can discuss it on hotspot-dev at oopenjdk.java.net.
