This is expected behavior if the cache directory is readonly. If you want the cache directory somewhere other than the default, you can set the "python.cachedir" property to some other location. If you don't want caching at all you can set "python.cachedir.skip = true". More here: http://www.jython.org/jythonbook/en/1.0/ModulesPackages.html#how-jython-finds-the-jars-and-classes-to-scan
