Even with reflection, is it possible?  I was just playing around with 
reflection and I noticed that the API only promises to return public 
methods and fields.  Maybe there's a sneaky "getAll" that I missed...

Anyway, calling super here is probably the best choice. Note than in 
your example you must call super because Bar has no default constructor.

One can also provide a factory method such as newInstance below.

package attribs;

public class Foo extends Bar {
   private String id;
   public Foo(String name,String id){
     super( name );           // New line here
     //this.name = name;      // Get rid of this one
     this.id = id
   }
   static public Foo newInstance( String id ) {
     Foo f = new Foo( "default", id );
     f.setSomeOtherNonfinalProperty( "non" );
     return f;
}

package attribs;

public class Bar {

   private String name;

   public setName(String name) {this.name = name;}
}
