Summary: jythonc --deep pjy$packages problem

Initial Comment:

Hi!
I've noticed a problem with the java code created by
jythonc.


In order to reproduce the problem, we need the
following two files, foo.py and bug.py.

------------------- foo.py -------------------------

import java

class foo(java.lang.Object):
    pass

----------------------------------------------------

--------------- bug.py -----------------------------

from foo import foo

class bar(foo):
    pass

----------------------------------------------------




When compiling this with
    jythonc --deep bug.py
I get the following messages:

    ERROR DURING JAVA COMPILATION... EXITING
---------------------------------------------------------------

Experiments suggest that the following circumstances
are necessary to
trigger the bug.
    1. The class foo is derived from a java class.
    2. The name of the module (foo) is the same as the
name of the
    class. 
    3. The whole thing gets compiled with the --deep
option.

Note that these three conditions are not sufficient to
trigger the bug;
I've got examples satisfying both 1. and 2. that
compile just fine.
Best,
