In preparation for ~~JDK-8072498~~ and also in preparation for desired changes for low-latency collectors like ZGC and Shenandoah, we need to be able to process JNI global and weak global handles either in parallel, concurrently, or both. The JNI handle implementation doesn't presently support any of those use-cases, and even has existing concurrency issues (~~JDK-8174790~~).
