Description

• There is a resource leak in RDFConnectionAdapter:

  public class RDFConnectionAdapter implements RDFConnection {
  
      @Override
      public QueryExecution query(Query query) {
          QueryExec queryExec = get().query(query); // This line leaks resources
          return adapt(get().query(query));
      }
  
  }
  

• Also, please make access to the underlying links in RDFLinkModular public in order to reduce the amount of re-wrapping needed when e.g. only only wrapping the LinkSparqlQuery with custom query rewriting.
