Under CPython the filehandle will be automatically garbage collected.
Under JPython (Jython) it won't be...
Isn't it rather that CPython will close the file as soon as the last reference is dropped, which is probably right after the read returns?
Whereas Jython/Java will close the file, when the garbage collector actually reclaims the object, which will be later. Or much later.

It isn't that difficult to write a small function to that effect.
It would perhaps be wise to acknowledge the existence of Jython and IronPython by allowing an additional flag for open to the effect "close when the end of the file is reached". This would prevent similar problems with iter (open (...)), which can't be wrapped quite as easily.
