Summary: Importing java-classes from non-defaul ClassLoaders

Details: I have my own classloader, which loads Jython also.
When I run this 

+++++++
package a.b.c
import org.python.util.PythonInterpreter;
import org.python.core.*;

public class Test{

    public static void main(String args[]) throws Exception  {
    
        PythonInterpreter interp = new PythonInterpreter();
        interp.exec("from a.b.c import Test");
        interp.exec("s = Test.countLetters('wednesday')");
        PyObject x = interp.get("s");
        System.out.println("s=" + x);
   }

    public static String countLetters(String str){
        return "Word '"+str+"' has "+ str.length() + " letters";
    }

}
++++++++++++++++
I have 
"ImportError: no module named a"

But when I explicitly write my.jar(a.b.c.Test) to classpath - everithing is
Ok.

What about usin' Thead.getContextClassLoader() in Py.findClass() or
something?

Comment:
more a feature request than a bug. (sorry)

notes:
 * simply making java loading through 'import' thread-context-class-loader
related: a bad confusing hack, won't do that
 * simply setting PySystemState.classLoader at init:
  not really a workaround, by now too many jythonc-related
  side-effects, e.g. sys.path loading disabled ...

This is part of the poor-man-freezing design issue
(after 2.0):

with jython -jar ... or java -jar ...

what kind of:
 python importing
 java loading
 sys-package-manager init
to offer? ...
