@nityarai08 ,

What macOS and Xcode versions are required to support VM_MEMORY_JAVA tag?

OpenJDK macOS recommendation:

It is recommended that you use at least macOS 14 and Xcode 15.4, but earlier versions may also work.

It would be nice to have a gtest.

Imo, be a good idea to include os/bsd/gc/z/zPhysicalMemoryBacking_bsd.cpp, which has 3 uses that should probably be marked with VM_MEMORY_JAVA. #if defined(APPLE) of course.
