Aklakan opened a new issue, #3516: URL: https://github.com/apache/jena/issues/3516
### Version 5.7.0-SNAPSHOT ### What happened? From https://www.mail-archive.com/[email protected]/msg21185.html Sparql query execution may give this error: ``` Cannot invoke "org.apache.jena.sparql.engine.join.MultiHashProbeTable.clear()" because "this.hashTable" is null ``` Reason is an oversight from https://github.com/apache/jena/pull/3047 - This PR initialized the hash table only lazily - but if the iterator is closed without use (call to next/hasNext) then the close method raises an NPE. ### Relevant output and stacktrace ```shell ``` ### Are you interested in making a pull request?
