I encountered this exact problem with modjy, which broke after jython
2.5b0. I reported it as an issue

http://bugs.jython.org/issue1171

The cause was a backwards incompatible API change.

You need to change your code as described in that issue.

If you need for your code to work on all versions, you can do what modjy
now does, as follows

try:
    from org.python.core.util import FileUtil
    create_py_file = FileUtil.wrap
except ImportError:
    from org.python.core import PyFile
    create_py_file = PyFile

my_file = create_py_file(FileInputStream("in.txt"))

HTH.
