[<no...@so...>]

Summary: Can't acces public member of package private base class

Details: For some reason, JPython cannot access a public method that is
defined
in the package private base class of my object instance.  public Foo 
extends (package private) Bar.  Bar defines public String hi().  If I 
instantiate Foo and call hi() on the instance, I get an
IllegalAccessException.

Java classes:
--------------------------------------------------------------
package testpackage;

public class Foo extends Bar {
}

class Bar {
    public String hi() {
        return "hi";
    }
}
---------------------------------------------------------------

Python code:
---------------------------------------------------------------
>>> from testpackage import Foo
>>> f = Foo()
>>> f.hi()
---------------------------------------------------------------

Resulting exception:
---------------------------------------------------------------
Traceback (innermost last):
  File "<console>", line 1, in ?
java.lang.IllegalAccessException: testpackage/Bar

Comment:
this is a similar bug to #132462
I've altered a few methods in PyJavaClass and added another Options flag
to use the JavaAccessibility.setAccessible()  to "mimic" the equivalent
Java access. (Now if I can only give jython classes access to protected
members
of Java super classes!)

Comment:
I don't think this is solvable at all! The method is accessible through
java but inaccessible through reflection!
