Possibility of backporting fix for JDK-6986863

[Harald Kuhr]

Thanks,

I’ve created the PR: https://github.com/openjdk/jdk11u/pull/14

But as this is my first PR agains OpenJDK, I am uncertain if I need a new issue on JDK 11 to be able to merge, or can I refer the existing (6986863) issue? It seems a new issue is required, I am not able to file issues in the current OpenJDK issue tracker, which leaves me with a kind of catch-22… Any advice on how to proceed would be appreciated!

Also my OCA is signed but pending verification, so I guess I just have to sit back and wait for a while. 


Best regards,
