Hi,

I'm trying to parse (even mime type detect) some XML file that it's not large, 
but kinda tricky and my process hangs on :

XMLStringBuffer.append(char[], int, int) line: not available 
XMLStringBuffer.append(XMLString) line: not available 
XMLNSDocumentScannerImpl(XMLScanner).scanAttributeValue(XMLString, XMLString, 
String, boolean, String) line: not available 
XMLNSDocumentScannerImpl.scanAttribute(XMLAttributesImpl) line: not available 
XMLNSDocumentScannerImpl.scanStartElement() line: not available 
XMLNSDocumentScannerImpl$NSContentDispatcher.scanRootElementHook() line: not 
available 
XMLNSDocumentScannerImpl$NSContentDispatcher(XMLDocumentFragmentScannerImpl$FragmentContentDispatcher).dispatch(boolean)
 line: not available 
XMLNSDocumentScannerImpl(XMLDocumentFragmentScannerImpl).scanDocument(boolean) 
line: not available 
XIncludeAwareParserConfiguration(XML11Configuration).parse(boolean) line: not 
available 
XIncludeAwareParserConfiguration(XML11Configuration).parse(XMLInputSource) 
line: not available

available

available 
SAXParserImpl$JAXPSAXParser.parse(InputSource) line: not available 
SAXParserImpl.parse(InputSource, DefaultHandler) line: not available 
SAXParserImpl(SAXParser).parse(InputStream, DefaultHandler) line: 195 
XmlRootExtractor.extractRootElement(InputStream) line: 62

MimeTypes.getMimeType(byte[]) line: 212 
MimeTypes.detect(InputStream, Metadata) line: 494

Please see attached XML file.

Please advise.
