-----------------------------------
Summary: Compresses JSON-LD test
AbstractNodeTupleInputFormatTests.fail_on_bad_input_02 no longer catches
IOException.
Key: JENA-1013
URL: https://issues.apache.org/jira/browse/JENA-1013
Project: Apache Jena
Issue Type: Bug
Components: Elephas
Affects Versions: Jena 3.0.1
Reporter: Andy Seaborne
In fixing JENA-1011, specifically, correctly calling the JSON-LD parser with
nested start/finish calls to the RDFStream, test
{{AbstractNodeTupleInputFormatTests.fail_on_bad_input_02}} now fails on JSON-LD.
The reason is that the test data has junk after the closing {{\}}} but the
JSON-LD parser (for better or worse) actually ignores trailing content and
stops parsing when the matching object close-} is seen. The input stream is in
an unclear state (caching read-ahead) but the parser does not advance any
further so it does not report an error.
In order to get an IOException, the test would need to continue parsing after
the end of the legal top level JSON object - effectively, it needs to restart
the parser. jsonld-java has already finished at this point - the call of
{{JsonUtils.fromInputStream}} does not look beyond the end of top level object.
This shows up in the piped iterator because the call to RDFStream.finish()
closes the iterator neatly.
