---- Migration to java.net.http:
* HTTP usage provided by the JDK java.net.http package, with
challenge-based authentication provided on top by Jena.
* Execution objects (QueryExecution, UpdateExecution, RDFConnection)
have a companion builders for detailed configuration. Previous factory
classes remain but builders are preferred.
This is especially important for HTTP as there many configuration
options that may be needed (including template queries).
* Timeouts - remote only supports the overall query execution.
(connection timeout on HttpClient but due to connection caching and now
HTTP/2 it is unclear how meaningful that is per request)
* HTTP/2 support (comes from using java.net.http package)

Checking needed:
+ are the GPG signatures fine?
+ are the checksums correct?
+ is there a source archive?
+ can the source archive be built?
(NB This requires a "mvn install" first time)
+ is there a correct LICENSE and NOTICE file in each artifact
(both source and binary artifacts)?
+ does the NOTICE file contain all necessary attributions?
+ have any licenses of dependencies changed due to upgrades?
if so have LICENSE and NOTICE been upgraded appropriately?
+ does the tag/commit in the SCM contain reproducible sources?
