If a classifier member has the same name as an inherited member, an error is not reported when also inheriting an unnamed mode transition. The following model should produce an error, but it doesn't:

package duplicate_name
  system s
      e: in event port;
      m1: initial mode;
      m2: mode;
      m1 -[e]-> m2;
  end s;

  system implementation s.i1
      sub: abstract;
  end s.i1;

  system implementation s.i2 extends s.i1
      sub: system;
  end s.i2;
end duplicate_name;

Giving the mode transition a name will cause an error to be reported on sub in s.i2. The problem is that the validator assumes that all NamedElements have a non-null name. This results in a NullPointerException which aborts that validation. A null check needs to be added here:

&& ((NamedElement) ownedElement).getName().equalsIgnoreCase(ne.getName())) {
