[aarch64-port-dev ] RFR: 8195685: AArch64: AArch64 cannot build with JDK-8174962

[jesper.wilhelmsson at oracle.com]

Hi Andrew,

Please note that we are now in RDP2 and there is a process to follow to include the fix: http://openjdk.java.net/projects/jdk/10/rdp-2 <http://openjdk.java.net/projects/jdk/10/rdp-2>

In particular you need to add the label jdk10-fix-request to the JBS issue to alert the release team about this bug. If not they don't know that they have to wait for your fix to get done.

Please don't just add the label though, there is more to it.

Thanks,
/Jesper
