Jena-2.11.2 QueryParseException: Encountered ""as""as ""

Hi All,

I have encountered a problem when using Jena. The query can be executed on http://dbpedia.org/sparql/ correctly, but failed in Java code.
Could anyone help me? I tried find solution online but failed. Some links said it's the version problem, but I think 2.11.2 is new.

Here's the code

String QueryOrg= "select distinct ?Apro (count(distinct ?n0) as ?Num) " +
"where{ " +
"?n0 a <http://dbpedia.org/ontology/TelevisionStation>. " +
"?n0 a <http://dbpedia.org/class/yago/CBSNetworkAffiliates>. " +
"?n0 ?Apro ?o. " +
"FILTER IsLiteral(?o) " +
"} " +
"group by ?Apro " +
"having(count(distinct ?n0) as ?tt >1) " +
"order by DESC(?Num) " ;

Query query = QueryFactory.create(QueryOrg);
// I have not do anything yet

The error:
"Exception in thread "main" com.hp.hpl.jena.query.QueryParseException: Encountered " "as" "as "" at line 1, column 260.
Was expecting one of:
