[GitHub] [jena] Aklakan opened a new issue, #1393: [Bug] QueryExecutionAdapter.adapt returns null
Aklakan opened a new issue, #1393:
URL: https://github.com/apache/jena/issues/1393
### Version
4.6.0-SNAPSHOT
### What happened?
There is another bug in the Exec/Execution machinery that QueryExecAdapter.adapt returns null as shown in the example below.
I keep this bug report separate from #1390 which is about adding to (rather fixing) infrastructure.
```java
@Test
public void testQueryExecAdapter() {
try (QueryExecution qExec = QueryExecutionFactory.create("SELECT * { ?s ?p ?o }", DatasetFactory.empty())) {
QueryExec qe = QueryExecAdapter.adapt(qExec);
Assert.assertNotNull(qe); // FAILS!
}
}
```
QueryExecAdapter attempts to do certain things lazily; I can look into it but probably @afs knows better how to fix it w.r.t. what he had in mind :)
### Which environment is running?

- [ ] Linux

### Relevant output and stacktrace
