I'm using jython2.5.1 in MATLAB's JVM. Upon trying to parse an XML file with ElementTree, XMLParser.__init__ tries to get XMLReaderFactory to find "org.python.apache.xerces.parsers.SAXParser". Probably due to limitations in MATLAB's stupid classloader, this does not work (throws a SAXException/ClassNotFoundException) The only relevant comment on why this weird name is used is expat.py line 51: "Name mangled by jarjar?". Manually setting expat._xerces_parser to "org.apache.xerces.parsers.SAXParser" resolves the issue. Perhaps a try block around the XMLReaderFactory call?
