Issue1147

Jython fails to resolve references to static nested classes when
referenced through a subclass.

For an example, assume you have the hierarchy:

public class Base {
    public static class NestedBase {
        public static final int ONE=1;
    }
}

public class Child extends Base {
}

Then in jython:
print "Child.NestedBase.ONE=%d" % (Child.NestedBase.ONE)

This will throw:
AttributeError: class 'Child' has no attribute 'NestedBase'

even though the reference is valid in Java.

The uploaded patch uses java.lang.Class.getClasses() to obtain
references to nested classes.

Don't know if there are any performance considerations here, but doesn't
seem like it would be slower than loading the class...

One more note -- this patch does not produce any new regressions in tests.

Ran the regrtest build target on both the pristine trunk and patched
trunk and both produce the same output on my setup:

     [exec] 265 tests OK.
     [exec] 5 tests skipped:

Hey Charlie, since PyJavaClass is in a little flux lately, I didn't want
to try to apply this just in case you are working nearby.  I assigned
this to you, but If the dust has settled and you want to assign this
back to me, go ahead.

Applied in r5523.  Thanks!
