I am unable to use https JSON-LD @contexts - something with https is not working. Basically this breaks anything at https://w3id.org/ which is popular in JSON-LD community.

This was broken in 3.0.0, 3.0.1 and 3.1.0 RC3.  

Upgrading JSON-LD Java to 0.8.2 and corresponding httpclient/httpclient-cache/httpcore seems to fix the issue.


{code}
stain@biggie:~/Downloads/95/apache-jena-3.1.0$ bin/riot --syntax jsonld
{"@context": "https://w3id.org/bundle/context.json", "aggregates":
"http://example.com/soup" }
17:04:59 ERROR riot                 :: invalid remote context:
https://w3id.org/bundle/context.json
{code}

Trying to follow the redirection does not help, as it goes to https as well:

{code}
stain@biggie:~/Downloads/95/apache-jena-3.1.0$ bin/riot --syntax jsonld
{"@context": "https://rawgit.com/researchobject/specifications/gh-pages/bundle/context.json",
"aggregates": "http://example.com/soup" }
17:05:59 ERROR riot                 :: invalid remote context:
https://rawgit.com/researchobject/specifications/gh-pages/bundle/context.json
{code}

Using http instead of https works - so the context is not at fault:

{code}
stain@biggie:~/Downloads/95/apache-jena-3.1.0$ bin/riot --syntax jsonld
{"@context": "http://rawgit.com/researchobject/specifications/gh-pages/bundle/context.json",
"aggregates": "http://example.com/soup" }
_:B9c444c8e486c7be3e4a49bbaaff22bc8
<http://www.openarchives.org/ore/terms/aggregates>
<http://example.com/soup> .
{code}

So I tried with another w3id-identified context, which also fails:

{code}
stain@biggie:~/Downloads/95/apache-jena-3.1.0$ bin/riot --syntax jsonld
{"@context": "https://w3id.org/payswarm/v1", "paymentMethod": "Visa" }
17:07:45 ERROR riot                 :: invalid remote context:
https://w3id.org/payswarm/v1
{code}

I get the same errors with 3.0.0 and 3.0.1, so perhaps this is not a
blocker for this RC.


Dropping in lib/httpclient-4.5.1.jar  lib/httpclient-cache-4.5.1.jar
lib/httpcore-4.4.4.jar  lib/jsonld-java-0.8.2.jar

fixes this issue for both cases:

{code}
stain@biggie:~/Downloads/95/apache-jena-3.1.0$ bin/riot --syntax jsonld
{"@context": "https://w3id.org/payswarm/v1", "paymentMethod": "Visa" }
_:Bbd3ab47b6dc78802bd11266c6dff7b5c
<https://w3id.org/commerce#paymentMethod>
<https://w3id.org/commerce/creditcard#Visa> .
{code}

{code}
stain@biggie:~/Downloads/95/apache-jena-3.1.0$ bin/riot --syntax jsonld
{"@context": "https://w3id.org/bundle/context.json", "aggregates":
"http://example.com/soup" }
_:B4c8067a2a952151f5b2251f8a35c53dc
