> CONSTRUCT-Sparql-Request fails with "no result format specified or unsupported format". 
> In SparqlWebService.select an extensive request header parsing is done to determine the best content type to use for the response. 
> Reason: in the above environment - the method 
> {code:java}
>  List<String> acceptHeaders = EnumerationUtils.toList(request.getHeaders(ACCEPT));
> {code}
> does not produce a list with each requested accept header, instead a list with a single entry containing all accept headers is created - example below:
> {code:java}
> "application/n-triples;q=0.7, text/plain;q=0.7, application/rdf+xml;q=0.8, application/xml;q=0.8, text/turtle, application/x-turtle, application/trig;q=0.8, application/x-trig;q=0.8"
> {code}
> This string is then further parsed with 
> {code:java}
> List<ContentType> acceptedTypes = HttpMarmottaUtils.parseAcceptHeaders(List<String>) 
> {code}
> where the string is split into tokens. Problem: the leading space after each comma (",") is not stripped!!
> Solution: in MarmottaHttpUtils.java, method "parseContentType", each token should be trimmed - line 132.
> {code:java}
> String mt[] = c.trim().split(";");
> {code}
> Just provided the patch to "develop" branch
