Hi - could you raise an issue for this please.
There's a backlog at th emoment so don't want to loose it.
Andy
PS the difference is that there are newlines in the
con.query(Query) form and not in the con.query(String) form - add a \nb
and I expect it will also break.

I changed
QueryExecution qe = con.query(query);
to
QueryExecution qe = con.query("select ?s where {?s ?p ?o} limit 10");
and it works. A bug in the former method? - Erich

Thanks Andy, this is a huge help.
using this code:
Query query = QueryFactory.create("select ?s where {?s ?p ?o} limit 10");
AuthEnv.get().registerUsernamePassword(new URI("
https://myserver.edu/sparql-auth";), Settings.user, Settings.password);
HttpClient client = HttpClient.newBuilder()
.connectTimeout(Duration.ofSeconds(10))
.version(HttpClient.Version.HTTP_1_1)
.build();
RDFConnection con = RDFConnectionRemote.create()
.destination(host)
.queryEndpoint("sparql-auth")
.httpClient(client)
.build();
QueryExecution qe = con.query(query);
ResultSet results = qe.execSelect();
is throwing an error:

It seems in Jena 4.3.X forward HttpClient in RDFConnectionRemoteBuilder
was
changed from org.apache.http.client.HttpClient to
java.net.http.HttpClient.
The latter doesn't appear to support Digest Authentication. Is there
support for Digest authentication in 4.3.X forward? I was able to do it
with the older RDFConnectionRemoteBuilder. Thanks, Erich
https://jena.apache.org/documentation/sparql-apis/
Digest auth is supported (implemented by Jena).
