When calling some tests a validation error is thrown:
Error in call to extension function {public org.w3c.dom.NodeList com.occamlab.te.TECore.request(org.w3c.dom.Document,java.lang.String) throws java.lang.Throwable}: Exception in extension function java.lang.Exception: Error invoking parser {http://www.occamlab.com/te/parsers}XMLValidatingParser org.xml.sax.SAXParseException: schema_reference.4: Failed to read schema document 'http://www.w3.org/2001/xml.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>.</xsd:schema>
This blogs explains the issue: http://www.w3.org/blog/systeam/2008/02/08/w3c_s_excessive_dtd_traffic/
The method is in com.occamlab.te.TECore.java is at line 1177: public static File getFile(NodeList fileNodes). Maybe we can add extra code, so instead of throwing an exception, when the schema is not available via URL, it trys to find it in the resources or class path.
