Description

Riot could remove the URL anchor before sending the HTTP request.
It's better in Jena code than in my code !

Here is an interactive session to demonstrate the problem:

 scala> import org.apache.jena.riot._
 import org.apache.jena.riot._

scala> RDFDataMgr.loadGraph( "http://raw.githubusercontent.com/jmvanel/semantic_forms/master/scala/forms/form_specs/login.form.ttl#registerForm")
 ERROR StatusLogger No log4j2 configuration file found. Using default configuration: logging only errors to the console. Set system property 'log4j2.debug' to show Log4j2 internal initialization logging.

// But this works:
