It's not clear from the information so far.
Complete, minimal, verifiable example please.
Also - what's the stacktrace you are seeing and which Jena version are
you running?

Hi,
I'm trying to understand in which circumstances can the following code
try (QueryExecution qex = QueryExecution.create(getQuery(), rowModel))
{
return qex.execConstructDataset();
}
throw the "HTTP QueryExecution has been closed" exception?
Full code here:
https://github.com/AtomGraph/LinkedDataHub/blob/rf-direct-graph-ids-only/src/main/java/com/atomgraph/linkeddatahub/imports/stream/csv/CSVGraphStoreRowProcessor.java#L141
The execution is not even happening over HTTP? Is it somehow closed prematurely?
I can see the exception being thrown in QueryExecDataset::constructQuads:
