@HotSpotIntrinsicCandidate and native prefixes

If you set a native prefix using SetNativeMethodPrefix, in order to wrap
native methods. If those methods are annotated with @HotSpotIntrinsicCandidate
you get a warning when running.

For instance for Thread::isInterrupted:
Compiler intrinsic is defined for method
[java.lang.Thread.isInterrupted(Z)Z], but the method is not annotated with
@HotSpotIntrinsicCandidate. Method will not be inlined.
Method [java.lang.Thread.$prefix$isInterrupted(Z)Z] is annotated with
@HotSpotIntrinsicCandidate, but no compiler intrinsic is defined for the

Shouldn't the native prefix be taken into account for this?

Kind regards
