I've extended this to cover the case in
sun.security.provider.ByteArrayAccess, as with
the ppc64 version, and pushed it:

http://hg.openjdk.java.net/aarch64-port/jdk8u/jdk/rev/64e09337b9b7
https://bugs.openjdk.java.net/browse/JDK-8186090

For future contributions, can you please include the patch as an
attachment as they
otherwise get mangled by the mail system.

Thanks,
