Stay away from reflection for this.

To call setName() from the constructor safely, the method must be final. 
Non-final methods called from a constructor are a major risk factor.

Really the superclass needs a constructor with a name argument, if it's 
intended that subcl***** extend off the name.  Since Bar does not have a 
constructor that takes 'name', then its subcl***** should not try to
construct 
the with a parent 'name'.  If Bar did have a 'public Bar( String name )' 
constructor, then Foo would invoke that:

public Foo( String name )
{
   super( name );
}

You cannot directly access private members of other cl*****.
