-------------------------------------
Java 9 httpclient had

where in java 16
([https://docs.oracle.com/en/java/javase/16/docs/api/java.net.http/java/net/http/HttpClient.Redirect.html])
this has changed to:
Description
{{[ALWAYS|https://docs.oracle.com/en/java/javase/16/docs/api/java.net.http/java/net/http/HttpClient.Redirect.html#ALWAYS]}}
Always redirect.
{{[NEVER|https://docs.oracle.com/en/java/javase/16/docs/api/java.net.http/java/net/http/HttpClient.Redirect.html#NEVER]}}
Never redirect.
{{[NORMAL|https://docs.oracle.com/en/java/javase/16/docs/api/java.net.http/java/net/http/HttpClient.Redirect.html#NORMAL]}}
Always redirect, except from HTTPS URLs to HTTP URLs.
It seems "secure" has been renamed to "normal" although it's a bit of a mystery
why the behavior would change regarding 303 handling (if it actually has).
Maybe the URL I'm using is responding a bit differently since the initial issue
since an insecure redirect from https -> http appears to be in play from
[https://purl.org/iso25964/skos-thes] to
[http://pub.tenforce.com/schemas/iso25964/skos-thes]
I suppose one course of action is to point out this problem to the maintainer
of the final URL, although it would be nice to have a slightly more obvious way
of dealing with this in Jena when / if it arises.
> 303 redirect issues cropped up again in 4.3 snapshot

> Key: JENA-2203
> URL: https://issues.apache.org/jira/browse/JENA-2203
> Project: Apache Jena
> Issue Type: Improvement
> Affects Versions: Jena 4.3.0
> Reporter: David Beaudet
> Assignee: Andy Seaborne
> Priority: Major
>
> The same issue noted in #JENA-1263 with 303 redirects not being followed when
> loading ontologies seems to have cropped up again in version 4.3.0 and
> requires the following workaround in client code:
> static {
> HttpEnv.setDftHttpClient(
> HttpClient.newBuilder()
> .connectTimeout(Duration.ofSeconds(10))
> .followRedirects(Redirect.ALWAYS)
> .build()
> );
> The default builder sets Redirect.NORMAL which, at least in the latest
> versions of Java (I'm using OpenJDK 16) doesn't appear to follow 303.
>
> Can reproduce with the following:
> OntModel data =
> ModelFactory.createOntologyModel(OntModelSpec.OWL_DL_MEM_RULE_INF);
> data.read("http://purl.org/iso25964/skos-thes";);
