I created https://github.com/apache/jena/issues/3516 and added a
possible fix.
A minimal query/data sample would of course be helpful to ensure that
this really fixes your issue.
Cheers,

Hello,
We've been getting the following error from the last 4 releases of
jena-fuseki: (5.3.0 onwards)
Cannot invoke
"org.apache.jena.sparql.engine.join.MultiHashProbeTable.clear()" because
"this.hashTable" is null
The SPARQL query is quite complex and there is a dependency on the RDF data
as well, so for now I don't have any more details, but I'd be curious if
you have any suggestions on what could cause this, or how to fix it.
Thanks,
Gaspar
