Andy Seaborne resolved JENA-444.
--------------------------------
Resolution: Fixed
Fix Version/s: Jena 2.10.1
Assignee: Andy Seaborne
Fix applied for formatting the OpAsQuery generated syntax. Its was general
facing of the formatter but extremely unlikely in a normal query. Howver,
OpAsQuery only guarantees to generate equivalent queries and would find it hard
to rebuild the original form so it generates syntax structure that gets the
same results but is a different syntax tree.
> "Error 500: java.nio.charset.MalformedInputException: Input length = 1" for a
> federated SPARQL query with multiple triple patterns (in inner query), where
> one of them uses SPARQL property paths

> Key: JENA-444
> URL: https://issues.apache.org/jira/browse/JENA-444
> Project: Apache Jena
> Issue Type: Bug
> Components: Fuseki, Jena, TDB
> Affects Versions: Jena 2.10.1, TDB 0.10.1
> Environment: Ubuntu
> Reporter: Sarven Capadisli
> Assignee: Andy Seaborne
> Fix For: Jena 2.10.1
>
>
> The following query throws HttpException:
> java.nio.charset.MalformedInputException: Input length = 1:
> java.nio.charset.MalformedInputException: Input length = 1 (whether query is
> requested over Fuseki or TDB)
> At SPARQL endpoint: http://transparency.270a.info/sparql
> PREFIX qb: <http://purl.org/linked-data/cube#>
> SELECT *
> WHERE {
> SERVICE <http://worldbank.270a.info/sparql> {
> SELECT ?observationX ?componentMeasureX
> WHERE {
> <http://worldbank.270a.info/dataset/AG.AGR.TRAC.NO>
> qb:structure/qb:component/qb:measure ?componentMeasureX .
> ?observationX qb:dataSet
> <http://worldbank.270a.info/dataset/AG.AGR.TRAC.NO> .
> }
> }
> }
> Some test results:
> * If either one of the triple patterns in the inner query is commented out,
> the query returns a response
> * The inner query alone returns a response if done at
> http://worldbank.270a.info/sparql
> * If a SPARQL property path inside SERVICE is not the only triple pattern, it
> throws an error.
