             Summary: Round tripping property paths from SPARQL into Sexpressions and back yields a syntax error
                 Key: JENA-989
                 URL: https://issues.apache.org/jira/browse/JENA-989
             Project: Apache Jena
          Issue Type: Bug
          Components: ARQ
    Affects Versions: Jena 3.0.0
            Reporter: Rick Moynihan


The following SPARQL query:

{quote}
SELECT ?uri WHERE {
  ?uri <http://www.w3.org/2000/01/rdf-schema#subPropertyOf>+ <http://purl.org/linked-data/sdmx/2009/dimension#refArea>
}
{quote}

When converted into an sse:

{quote}
(path
  ?uri
  (path+ <http://www.w3.org/2000/01/rdf-schema#subPropertyOf>)
  <http://purl.org/linked-data/sdmx/2009/dimension#refArea>)
{quote}

and converted back into a SPARQL query via OpAsQuery is syntactically invalid.  Note the misplaced `.`:

{quote}
SELECT  *
WHERE
  {  .
    ?uri (<http://www.w3.org/2000/01/rdf-schema#subPropertyOf>)+ <http://purl.org/linked-data/sdmx/2009/dimension#refArea>
  }
{quote}

The same seems to occur for all other property paths (e.g. those that use +, *, /, ^ etc...) 

This seems related to issues resolved in JENA-963.
