Right.  It's internal interface between JDK and hotspot. 
src/java.base/share/include wasn't the desired location for it and hence 
the relocation.

Would it be an alternative if the source location of these header files 
can be configured at build time so that other JVM implementor can build 
JDK with an alternate location?   I would expect that other VM 
implementation would have to do some work for any change to jvm.h 
regardless of where it's located.  The extra (hopefully minimal) work is 
to update its own copy of jvm.h.
