     I'd half-expect that a JDK8-compiled class file might contain
references to interfaces and so on that didn't exist in 7.  But
perhaps (1) you're lucky, or (2) Oracle used more care than I'd
given them credit for.

     Safest course: If you're going to execute with Java N, compile
with JDK <=N.
