you mean why "JDK-8208601: Introduce native oop barriers in C2 for OopHandle" is needed? It is a prerequisite for "JDK-8210158: Accessorize JFR getEventWriter() intrinsics" which ought to resolve a potential JFR crash. But if only the patch for 8210158 was used, it would not compile. I think it would e.g. miss the definition of Node* access_load in graphKit.hpp.

Best regards
Christoph
