Joshua Taylor created JENA-741:
----------------------------------
Summary: SPARQL replace causes query to crash when non-existent
group in replacement pattern
Key: JENA-741
URL: https://issues.apache.org/jira/browse/JENA-741
Project: Apache Jena
Issue Type: Bug
Components: ARQ
Affects Versions: Jena 2.11.0
Reporter: Joshua Taylor
If a replacement string uses a group that's not in the pattern, the whole query
crashes (as opposed to the value of replace just being an error value).
Version, query, and command line to reproduce:
{{
$ sparql --version && cat query.rq && sparql --query query.rq --data data.n3
