Sorry for not being clear enough (late hours I guess).

I was using Sphinx (Python Doc Generator) with Jython 2.5.3 and everything worked for me. But when I switched to Jython 2.7b1 my doc builds started to fail.

The problem is that the same exception is raised with different error numbers.

Jython 2.5 raises the following exception:
OSError: [Errno 17] File exists: ...
This exception is caught by Sphinx and err.errno is checked. Errno 0 & 17 are ignored.

But Jython 2.7 raises:
OSError: [Errno 20047] Unknown error: 20047: ...
which causes Sphinx to reraise the exception and ultimately to fail.
