3 weeks ago Reproduced outside Fuseki and reduced to smaller data.
The NPE occurs on the attempt to delete rdfs:range rdfs:subPropertyOf rdfs:range.
public static void testCaseGH2616() {
JenaSystem.init();
String PREFIXES = """
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>

""";
String queryString = PREFIXES + """
SELECT * {
VALUES ?s { rdfs:range rdfs:subPropertyOf }
?s ?p ?o .
}
""";
String updateString = PREFIXES + """
DELETE {?s ?p ?o}
WHERE {
VALUES ?s {
## Only this order, both needed, one single operation.
rdfs:range
rdfs:subPropertyOf
}
?s ?p ?o .
## Exclude this and there is no NPE
##FILTER ( ! ( ?s = rdfs:range && ?p = rdfs:subPropertyOf && ?o = rdfs:range ) )
## No effect - this isn't reached in the gathered triples to delete.
##FILTER ( ! ( ?s = rdfs:subPropertyOf && ?p = rdf:type && ?o = rdf:Property ) )
}
""";
String data = PREFIXES + """

rdfs:subPropertyOf rdf:type rdf:Property .
""";
Model base = RDFParser.fromString(data, Lang.TTL).toModel();
InfModel inf = ModelFactory.createRDFSModel(base);
// This is the delete order
System.out.println("==== Deletes preview:");
try ( QueryExecution qExec = QueryExecution.model(inf).query(queryString).build()) {
ResultSetFormatter.out(qExec.execSelect(),qExec.getQuery());
