Hi Xuelei,
I can definitely build JDK 12 (jdk repo) from source and apply your
attached patch and give it a try. As for JDK 11, I haven't been
following the version control discussions/process, does it have a
separate repo now? Or is it some branch within jdk repo itself? Either
way, once I know the right repo location, I can (and in fact prefer)
building that repo with this patch to give it a try.
