[jira] [Commented] (JENA-444) "Error 500:

> Key: JENA-444
> URL: https://issues.apache.org/jira/browse/JENA-444
> Project: Apache Jena
> Issue Type: Bug
> Components: ARQ, Jena
> 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.
> Full error:
> HttpException: java.nio.charset.MalformedInputException: Input length = 1: java.nio.charset.MalformedInputException: Input length = 1
