JDK 9 pre-review of JDK-6850612: Deprecate Class.newInstance since it violates the checked exception language contract

I'm sure I'm missing something obvious related to performance or security but, couldn't the exact same 'cachedConstructor' field be used for caching  Class.getConstructor(new Class[0]) as long as a constructor copy is returned?
That way the recommended workaround is near the same performance.
