fixed MARMOTTA-280
> SPARQL Timeout: Too many error messages and invalid transaction
> ---------------------------------------------------------------
>
> Key: MARMOTTA-280
> URL: https://issues.apache.org/jira/browse/MARMOTTA-280
> Project: Marmotta
> Issue Type: Bug
> Components: Triple Store
> Reporter: Sebastian Schaffert
> Assignee: Sebastian Schaffert
> Priority: Minor
> Fix For: 3.1-incubating
>
>
> When the new SPARQL timeout mechanism stops a running SPARQL query, the error
> log is filled with exception traces; this should not happen, the SPARQL
> evaluation should abort completely on such errors.
> Stack Traces:
> 11:21:19.926 ERROR o.a.m.k.s.p.KiWiSparqlConnection - error executing SPARQL
