Substantially, I think the patch is fine.

But, I do wonder if the new classes should be in sun.misc.*, not in jdk.internal.*. One of the
reasons to use sun.misc.* is to get the proper javac warning on use. jdk.internal is something that
is protected by module boundaries in JDK 9+, not available in 8u.
