--- Comment #2 from Andrew Haley <aph at redhat.com> ---
JDK 7 over-enthusiastically vectorizes this code (as an OSR method), and the
resulting vectorized loop has no safepoint check.  In contrast, JDK 8 unrolls
the inner loop but does not vectorize it.

The inner loop is finite but very long in duration.  Eventually the safepoint
times out.

While this is a real bug, it is so extremely contrived that I don't think this
is a high priority.

A question for the original poster: where did this code come from?
