title: XML dig sig error after upgrade to java7u25
body: <p>I have a Java application for signing XML documents. After upgrading Java to the latest version (Java7u25) it stops working. I get the following error:</p>
  
  <pre><code>javax.xml.crypto.dsig.XMLSignatureException:
  javax.xml.crypto.URIReferenceException: 
  com.sun.org.apache.xml.internal.security.utils.resolver.ResourceResolverException:
  Cannot resolve element with ID ...
  </code></pre>
  
  <p>Reverting back to java7u21 solves the problem. Is there any change in the XML Dig Sig API that causes this error?</p>
