Message12776

I made a short script (test.py) that is able to reproduce this error.
Attached the needed files.
In test.py are 2 links to get the needed jar-files (I reproduced the error with the help of an older version of SAXParser - that is the context where the error occurs in my production system)
I created also two shell-scripts to start the tests.
You must adapt the paths but this should be straight forward.

test271 yields the error "SystemError: __getattribute__ not found on type null. See http://bugs.jython.org/issue2487 for details." after a few seconds to minutes.
test272b2 yields another one "AttributeError: 'NoneType' object has no attribute 'getValue'" (but maybe the root-cause is the old issue) after several hours.
Interestingly enough the error either occurs "en masse" or does not at all.
Also if you do not send stdout somewhere else (e.g. /dev/null(), the error seems not to occur in this context.

Happy hunting!
