I am guessing that the invokeExact call could have been replaced by a simple weakly-typed invoke call in the framing code, and likewise with most of the other invokes (methodType, findSpecial) which are not caller-sensitive.
I was wondering that too, but don't wanna block the push. With some judicious squinting i can work out what is going on. Perhaps if there are other related code fixes in the pipe (e.g. for the FIXME) this test could then be updated if there is time.
