The methods

     javax.xml.xpath.XPath.evaluate(String, Object, QName)
     javax.xml.xpath.XPath.evaluate(String, InputSource, QName)
     javax.xml.xpath.XPath.evaluate(String, URL, QName)

do not throw IllegalArgumentException in case when a return type is not one of the types defined in
XPathConstants. The methods should throw the exception according to the javadoc.

The bug affects new JCK1.5 tests (not integrated yet):

   api/javax_xml/xpath/XPath/index.html#Evaluate[Evaluate052]
   api/javax_xml/xpath/XPath/index.html#Evaluate[Evaluate056]
   api/javax_xml/xpath/XPath/index.html#Evaluate[Evaluate062]

The following test fails running on JDK 1.5.0-beta-b32.
