Gradle not working on Jigsaw

> A trySetAccessible is possible although a @CS variant of accessCheck (like in MH.Lookup) might be more general. I think we need to be cautious about adding APIs here and so would be interesting to get some performance data here (I > don't think I've seen the bulk setAccessible used very often, it's almost always the instance method).

Jython seems to be doing a setAccessible on a lot of methods.  It catches SecurityException and ignores it.  Of course, JDK9 throws a different exception so the code is broken.
Further, the new exception is JDK9 only so the code needs to change to catch and ignore RuntimeException.


Comment from Jython:
Set public methods on package protected classes accessible so
that reflected calls to the method in subclasses of the
package protected class will succeed. Yes, it's convoluted.
