The following method of the class org.apache.xml.security.transforms.Transform
does not test if the contextChild parameter is null:
public static final Transform getInstance(
Document doc,
String algorithmURI,
Element contextChild)
I propose this modified code to fix this bug:
public static final Transform getInstance(
Document doc, String algorithmURI, Element contextChild)
throws InvalidTransformException {
HelperNodeList contextNodes = null;
if (contextChild != null) {
contextNodes = new HelperNodeList();
XMLUtils.addReturnToElement(doc, contextNodes);
contextNodes.appendChild(contextChild);
XMLUtils.addReturnToElement(doc, contextNodes);
}
return Transform.getInstance(doc, algorithmURI, contextNodes);
}
