SHORT SUMMARY:
Classcast exception when using non-default JAXP parser
INDICATORS:
Exception :
Exception in thread "main" java.lang.ClassCastException:
oracle.xml.parser.v2.DTD cannot be cast to org.w3c.dom.Element
at java.util.XMLUtils.load(XMLUtils.java:61)

COUNTER INDICATORS:
TRIGGERS:
Use of non-default JAXP parser (oracle xml parser xmlparserv2.jar) in this
case while making calls into java.util.XMLUtils.load method
KNOWN WORKAROUND:
Modify the parser used.
PRESENT SINCE:
N/A
HOW TO VERIFY:
Testcase presented in BugDB report. oracle xml parser "xmlparserv2.jar"
should be present in CLASSPATH before running testcase.
NOTES FOR SE:
Logged on jdk 6u22 with linux x86 platform

Fix is simple and suggested by submitter :

==
The error is in the line:

Element propertiesElement = (Element)doc.getChildNodes().item(1);

which is making an incorrect assumption about the in-memory structure
of the parsed XML document. Instead, it should access the document
element of the XML DOM tree using the standard DOM API getDocumentElement():

Element propertiesElement = doc.getDocumentElement();
