Issue1653

Whenever mixing Jython and Java class in the same package structure and the Java class is not explicitly mentioned in __init__.py, the module fails to find it in subsequent import calls.


from foo import bar // OK
from foo import Foo // ERROR

(Yes, we are able to mix java and jython code within the same structure since Jython 2.1 and managed to make it work under Jython 2.5.1 as well)

This is due to the fact that an PyModule is initialized once but  incomplete. Rather than to do a full initialization one could simply fix this by adding the following code to PyModule.

    @Override
    public PyObject __findattr_ex__(String name) {
        PyObject attr=super.__findattr_ex__(name);
        if (attr!=null)
            return attr;
        return impAttr(name);
    }


Problem found in 2.5.1 and 2.5.2b2

Raised it to major, as I would /really/ like to see this end up in 2.5.2 :)

Sorry, I did not complete the explanation
The above package structure would have been:

  foo/__init__.py # empty, only there primarily for namespace reasons
  foo/bar.py
  foo/Foo.class

Sounds reasonable, a minimally scoped fix. Marked high to be part of 2.5.2rc1

An apparent duplicate of #1464, which I recently closed because we didn't have a good idea of what to do here in terms of resolving the loading. Now we do. #1464 also a test case we potentially can leverage.

We will use this issue to track. Moving nosy list here too.

Applied patch in r7151. Marked pending since it still needs a unit test however, hopefully I will have time before 2.5.2rc1, but better to get it in now.

Much appreciated!

Hi Jim,

I noticed that the code ended up in Jython 2.5.2.
Thanks!

What stops you to close the issue: test-harness?

Looks like this can be closed.
