### Version 4.7.0-SNAPSHOT ### What happened? Credits to @SimonBin for spotting this issue. A bug in the class responsible for forming batches from an input iterator ([RequestScheduler](https://github.com/apache/jena/blob/main/jena-extras/jena-serviceenhancer/src/main/java/org/apache/jena/sparql/service/enhancer/impl/RequestScheduler.java#L58)) causes bulk requests to become cut off. There is an internal limit which is aimed to protect against reading too far ahead into the input iterator when forming a batch request but the implementation is flawed. ```sparql PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> PREFIX wd: <http://www.wikidata.org/entity/> SELECT ?s ?l { # Generate 300+ bindings here such as simply using SERVICE <https://query.wikidata.org/sparql> { SELECT DISTINCT ?s { ?s ?p ?o } LIMIT 400 } SERVICE <loop:bulk+5:https://query.wikidata.org/sparql> { SELECT ?l { ?s rdfs:label ?l FILTER(langMatches(lang(?l), 'en')) } ORDER BY ?l LIMIT 1 } } ``` ### Relevant output and stacktrace _No response_ ### Are you interested in making a pull request?
