Hi, It seems that the method name used in 8165793[1], "isParallelCapable", was a little too intuitive. An existing use of that method name has been uncovered (via NetBeans, in Eclipse Equinox). Because the newly added method was marked final, the pre-existing method results in a VerifyError under JDK 9 (for overriding a final method). Please review my fix, which makes ClassLoader.isParallelCapable() non-final. The semantics of such a boolean-returning isXXXX method are clear - it's unlikely that existing methods would use different semantics. I've included an @apiNote (ala ClassLoader.getName()) explaining that the non-final-ness here is strictly for compatibility.
