--------------------------------
Summary: LangJSONLD11 doesn't extract prefixes from context array
Key: JENA-2187
URL: https://issues.apache.org/jira/browse/JENA-2187
Project: Apache Jena
Issue Type: Bug
Components: ARQ
Affects Versions: Jena 4.2.0

Using riot cmdline, when processing a json-ld @context that is an array, I get
the following message, and the prefixes are not emitted in the ttl output.
{code:java}
10:46:02 WARN LangJSONLD11 :: Unexpected problem while extracting prefixes:

If the context is a JSON object, no warning message appears, and the prefixes
are included in the output.
