> Hi all,
> Currently on aarch64 platform the debug VM option `-XX:+VerifyActivationFrameSize` is Unimplemented. I want to implement `-XX:+VerifyActivationFrameSize` to make JVM easier to diagnose. Only effect debug build plus with option `-XX:+VerifyActivationFrameSize`, the change has been verified locally, the risk is low.
