DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setNamespaceAware(true);
DocumentBuilder builder = dbf.newDocumentBuilder();
final InputStream stream = new ByteArrayInputStream(xmlDoc.getBytes(StandardCharsets.UTF_8));

NodeList nl = doc.getElementsByTagNameNS(XMLSignature.XMLNS, "Signature");

XMLSignatureFactory factory = XMLSignatureFactory.getInstance("DOM");
// Unmarshal the XMLSignature.
XMLSignature signature = factory.unmarshalXMLSignature(valContext);
// Validate the XMLSignature.
boolean coreValidity = signature.validate(valContext);
I've add additional code for get reason of failure
// Check core validation status
if (coreValidity == false) {
System.err.println("Signature failed core validation");
boolean sv = signature.getSignatureValue().validate(valContext);
System.out.println("signature validation status: " + sv);
// check the validation status of each Reference
Iterator<?> i = signature.getSignedInfo().getReferences().iterator();
for (int j = 0; i.hasNext(); j++) {

System.out.println("ref[" + j + "] validity status: "

}
} else {
System.out.println("Signature passed core validation");
}
and have got this result
Signature failed core validation
signature validation status: false
ref[0] validity status: true
How to avoid signature validation false or how to debug the reason. at standard page there is information
Note, there may be valid signatures that some signature applications are unable to validate. Reasons for this include failure to implement optional parts of this specification, inability or unwillingness to execute specified algorithms, or inability or unwillingness to dereference specified URIs (some URI schemes may cause undesirable side effects), etc.
But how to avoid this problem. I know that signature is valid but ... One difference between good and wrong validated xml it's format reference id In good xml without - just digits or alphabets
