Description

Applying a NodeTransform to an ElementData has no effect due to a mistake in

org.apache.jena.sparql.syntax.syntaxtransform.ApplyElementTransformVisitor

    // BUGGED implementation as of Jena 3.6.0:
    @Override
    public void visit(ElementData el) {
        transform.transform(el) ;
        push(el) ;
    }

    // should be:
    @Override
    public void visit(ElementData el) {
        Element el2 = transform.transform(el) ;
        push(el2) ;
    }

    // analogous to:

    @Override
    public void visit(ElementOptional el) {
        Element elSub = pop() ;
        Element el2 = transform.transform(el, elSub) ;
        push(el2) ;
    }
