[aarch64-port-dev ] RFR: Backport patch for 7009641 to aarch64/jdk8u

[Felix Yang]

Hi,

    Please review: http://cr.openjdk.java.net/~fyang/7009641/webrev/
    We witnessed the same issue on aarch64 jdk8u port.
    Tested with JTreg, OK to push?
    Also can someone do a backport for the icedtea7 branch please?

Thanks,
Felix
