> h2. What is happening
> The exception happens when a property shape with sh:alternativePath is
> evaluated inside ConstraintComponentSPARQL. I'm not sure why however it only
> happens when dash/tosh shapes are imported by a shape.
> The exception seems to happen on line 239 of SparqlValidation.java:
> {{RDFNode z = ModelUtils.convertGraphNodeToRDFNode(ShaclPaths.pathNode(path),
> model);}}
> where pathNode() returns null - only supporting P_Link, not P_Alt and
> convertGraphNodeToRDFNode() then runs unchecked node.isVariable().
