XMLHelper.load() IOException using schema that has both a substitution group and an extension

Below, please find a failing Java test case and its XSD and XML test resources. Also, please find the stacktrace from the failing Java test case. It is interesting to note that this test does not fail when using dynamic SDO. Please comment if you have questions.
