Request for review (XS): Wrong filter predicate of visible locals in SA JSJavaFrame

There seems to be a bug in the filtering logic of visible local variable in Serviceability Agent's JSJavaFrame.

I've made a patch here: [1]. The diff is against tip of jdk8/jdk8/hotspot

An example of running CLHSDB before and after applying the patch is avaiable [2].

Could anyone please review this for me?
