I reported the same problem in http://bugs.jython.org/issue1204, not
having found this one in my search. I realize the case is closed, but I
wanted to record some background in case it ever gets revisited.

The application that broke for me was a unit test rig (and accompanying
application shell) that tested equivalent interfaces in both .NET (with
IronPython) and Java (with Jython). Jython and IronPython both allowed
constructing file objects from .NET/Java streams by using the file()
constructor, which I tried because it seemed obvious. And then I used it
because I had achieved compatibility without having to resort to some
adapter function.

I know it's rather odd to discuss feature parity with some other Python
implementation that isn't CPython. I've found it quite useful that the
two implementations are as compatible as they are.
