The cStringIO module in CPython says: # Close object and discard memory buffer -- # .getvalue() will now raise an exception I was expecting this to happen in a little script but it did not raise an exception (not relying on it, just testing some things out) In Jython 2.5.1 I close the StringIO object and it will still return the string buffer Looking at the source it looks like all close() does is set a flag. In reality it should clear out the buffer to free the memory and raise an exception if getvalue() is called after close

Your analysis is correct. I'm working on a fix.
