Issue in XMLScanner: EXPECTED_SQUARE_BRACKET_TO_CLOSE_INTERNAL_SUBSET when skipping large DOCTYPE section with CRLF at wrong place

Under certain circumstances, the following exception might occur during XML scanning:
Exception in thread "main" java.util.MissingResourceException: EXPECTED_SQUARE_BRACKET_TO_CLOSE_INTERNAL_SUBSET

Following is a small test to reproduce the behavior:
public static void main(String[] args) throws Exception {
StringBuilder xmlcontentbuilder = new StringBuilder(XMLEntityManager.DEFAULT_BUFFER_SIZE * 2);
xmlcontentbuilder.append("<?xml version=\"1.0\" encoding=\"ISO-8859-1\"?>\r\n");
xmlcontentbuilder.append("<!DOCTYPE dummy [\r\n");
xmlcontentbuilder.append(" <!ELEMENT dummy EMPTY>\r\n");
xmlcontentbuilder.append(" <!--\r\n");
xmlcontentbuilder.append(" ");
int textlen = XMLEntityManager.DEFAULT_BUFFER_SIZE - xmlcontentbuilder.length() - 2 - 1;
for (int i = 0; i < textlen; i++)
xmlcontentbuilder.append('a');
xmlcontentbuilder.append("\r\n");
xmlcontentbuilder.append(" -->\r\n");
xmlcontentbuilder.append(" ]\r\n");
xmlcontentbuilder.append(">\r\n");
xmlcontentbuilder.append("<dummy>\r\n");
xmlcontentbuilder.append("</dummy>\r\n");

XMLInputFactory factory = XMLInputFactory.newInstance();
factory.setProperty(XMLInputFactory.SUPPORT_DTD, false);
StringReader stringReader = new StringReader(xmlcontentbuilder.toString());
XMLEventReader reader = factory.createXMLEventReader(stringReader);

while (reader.hasNext()) {
XMLEvent event = reader.nextEvent();
System.out.println("Event Type: " + event.getEventType());
}
}
