Jim's example works on 7u2 for me as well.
The cast is not without effect at all. It is crucial to have it!
That is because of the so called "Signature polymorphism" of the
'invokeExact()' and plain 'invoke()' methods (read the API
documentation for more details:

Hi,
while running JCK test for our PPC port I realized that the test
'asCollectorIAE01' which checks valid and invalid 'arrayLength' arguments
to MethodHandle.asCollector() fails for the current 7u/jdk and jdk8/jdk

Hi everybody,
I've recently did some research on Java "value objects" / "value
types" / "object layout" (I'll be actually giving a short talk on the
topic at FOSDEM[0] this weekend). I just want to quickly summarize my
current findings here and gently ask for feedback in case you think

Hi Daniel,
thanks a lot for sharing your point of view.
I haven't been aware of the fact that Project Panama is also working

Function Interface and the next generation JNI). In [1,2] John Rose
nicely explains that new data layouts i

Hi Charlie,
not sure if it helps, but incidentally I currently have a change under
review [1] which chains the initial cause into NoClassDefFoundErrors.
If it helps you to track down the problem please feel free to mention that
