--- Comment #7 from Anna <anna at azul.com> ---
Thanks for the clarification Ayal. I didn't realize we already supported over
vectorization in the form of interleaving. The assertion we had downstream code
which operated on the vectorized code (some additional transformations are
needed for making java code safe to run in presence of GC) was incorrect.

I don't have a failing test case for normal code. Marking this bug as INVALID.
