Hotspot changes look good. Core-libs do too but I will leave that for libs folk to approve

src/java.base/share/classes/java/lang/reflect/Executable.java line 54:

If a field is listed here then it is NOT injected by hotspot.

src/java.base/share/classes/java/lang/reflect/Method.java line 73:

> 73:     // fields injected by hotspot

Again not injected
