In BA plugin, name resolution in actions fails when classifier with the same name exists

[Etienne13]

Summary

Name resolution fails when an action references the name of a contained element which is also a classifier name.

Expected and Current Behavior

The following example is correct but the BA plugin crashes with an exception:

package 2175
public

  thread function1
  features
	function2 : out event port;
  properties
    Dispatch_Protocol => Periodic;
    Period => 100 ms;
    Compute_Execution_Time => 1 ms .. 2 ms;
    Priority => 2;
  annex behavior_specification {**
  	states
  		s : initial complete final state;
	transitions
		s -[on dispatch]-> s{function2!};
  **};
  end function1;

  thread function2
  end function2;
  
end 2175;

Exception trace:

java.lang.UnsupportedOperationException: getFeatureType : ThreadTypeImpl is not supported yet at line 20.
