The function prototypes in jvm.h are JVM_* functions rather than JNI
native method names. You may want to look at adding a JNI function to
libjava with a wrapper or else use RegisterNatives to map the native
method name to a JVM_* function.
BTW: Is this something for one the project repos (Valhalla or Panama)
rather the main line (jdk/jdk)?
