The file jni.h is stored twice in the repo, both in hotspot and in
java.base. They are both identical, and only the java.base version is
included in the final product.
This bug is a part of the umbrella effort JDK-8167078 "Duplicate header
files in hotspot and jdk". As for JDK-8189607, my reasoning is that the
java.base version is the one to keep. (In this case, there was actually
a small difference between the two files -- the hotspot version first
copyright year was 1997, but the java.base version was 1996. It makes
sense to keep the oldest one.)
My assumption was that hotspot include files should be sorted according
to the containing directory, and since jni.h no longer resides in
"prims", I've rearranged the include line where needed.
The -I path added in CompileJvm.gmk is identical to the one in
JDK-8189607, and will be merged to the same change (depending on which
fix enters first.)
