>             Project: Santuario
>          Issue Type: Bug
>          Components: Java
>    Affects Versions: Java 1.4.2
>         Environment: Operating System: All
> Platform: PC

> 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);
> }
