public team class BT extends AT {

			tsuper();

}

Constructor call (tsuper) must be the first statement in a role constructor (OTJLD 2.4.2)

Each constructor of a role that is not bound to a base class must use one of this(..), super(..) or tsuper(..).

team class ATeam {
    public class R0 {}
    public class R1 extends R0 {}
}
team class BTeam extends ATeam { }
R1 createR1(final ATeam t) {
  return new R1<@t>();
}

Within role constructors all this(..) and super(..) calls are bound statically with respect to explicit inheritance and dynamically with respect to implicit inheritance. This means the target role name is determined statically, but using that name the suitable role type is determined using dynamic binding.

    protected class R0 {
        protected R0() { System.out.println("ATeam.R0()"); }

    protected class R1 extends R0 {
        protected R1() { System.out.println("ATeam.R1()"); }
   }
}
team class BTeam extends ATeam {
    protected class R0 {
        protected R0() { System.out.println("BTeam.R0()"); }
   }
    protected class R1  {
        protected R1() { System.out.println("BTeam.R1()"); }
   }
