-------------------------------------
Summary: QueryExecHTTP#actualSendMode ignores query length causing

Project: Apache Jena
Issue Type: Bug

{_}QueryExecHTTP#actualSendMode(){_}, called in {_}QueryExecHTTP#query(String
reqAcceptHeader){_}, does not consider the length of the query. In case of long
queries, this causes _414 Request-URI Too Long_ errors, even if
{_}sendMode=={_}{_}QuerySendMode{_}{_}.asGetWithLimitBody:{_}
