Description
JDK-8199620 introduced pin_object() and unpin_object() in CollectedHeap to allow pinning instead of GCLocker protocol for GCs that might prefer that. However, it lacks support for JNI critical functions, which may have performance impact on native code that takes advantage of JNI critical functions.
