I don't think you have to anything to "force" a Java method to be
interpreted first, because that's the default behavior already. Since you
only care about "non-zero" invocation counts, running a method in the
interpreter for even just once is enough, and it doesn't matter if the
method got compiled later.

So long as you don't do -Xcomp sort of stuff, you should get the correct
list of invoked methods this way. And with the -XX:-UseFastEmptyMethods
-XX:-UseFastAccessorMethods caveat.

Hopefully I'm not missing anything... :-)
