RFR(JDK12/java.xml) 8212871: Broken links give 401-Unauthorized

[Joe Wang]

Hi,

Please review a fix for the broken links, replacing:
http://www.w3.org/2002/08/WD-DOM-Level-3-XPath-20020820
with:
https://www.w3.org/TR/DOM-Level-3-XPath/

The former on which the jdk.xml.dom package was based is no longer 
publicly available. The later is current. The only difference between 
the two was noted in the package info ( 
src/jdk.xml.dom/share/classes/org/w3c/dom/xpath/package-info.java), and 
also in XPathException.java in this webrev.

JBS: https://bugs.openjdk.java.net/browse/JDK-8212871
webrev: http://cr.openjdk.java.net/~joehw/jdk12/8212871/webrev/

Thanks,
Joe
