Changes are fine.
I agree with Alan. Please, wait when we merge aarch64 stage into jdk9/dev and then push this fix into jdk9 (by sponsor).
We should finish testing of stage repo "soon".
Thanks,
Vladimir

because the runtime does not know that AArch64 can perform unaligned
memory accesses.
The problem is due to this code in java.nio.Bits.unaligned():
unaligned = arch.equals("i386") || arch.equals("x86")
|| arch.equals("amd64") || arch.equals("x86_64");
If we add AArch64 to this list code quality is very much improved.

Make sense, I assume this will go in when JEP 237 is pushed.
It will, but I need approval to push to the JEP 237 staging repo.
'Cos them's the rules. :-)
