[aarch64-port-dev ] Request for Approval: Backport patches to fix volatile access inconsistency

[Andrew Dinn]

Hi Felix,

Aleksey pointed out to me that patches 3 4 and 5 are not in jdk11u. You
will need to backport these to 11u before they can appear in
jdk8u-aarch64. So, please negotiate this via the jdkupdates mail list
and/or Fix-Requests on the relevant JIRAs.

Also, it will be necessary to backport each change to jdk8u separately
rather than committing all 5 as a single patch.

regards,


Andrew Dinn
