When doing a query with a language that does not exists jena throws an

works:
SELECT ?subject ?x ?label
WHERE {
?subject text:query (skos:prefLabel 'a' 'lang:nl')
}
exception:
SELECT ?subject ?x ?label
WHERE {
?subject text:query (skos:prefLabel 'a' 'lang:xx')
}
3.org/1999/02/22-rdf-syntax-ns#> SELECT ?subject ?x ?label WHERE { # ?subject
rdf:type skos:Concept . # skos:prefLabel ?label . #?subject rdf:type
skos:Concept; # ?subject skos:prefLabel ?prefLabel . ?subject text:query
(skos:prefLabel 'a' 'lang:te') # skos:prefLabel ?label # ?subject
skos:prefLabel ?label } LIMIT 100
