Type casts sind aktuell nicht implementiert.

Beispiel:

import java.lang.Object;
import java.lang.Integer;
import java.util.List;
import java.util.ArrayList;

public class Foo{
    public void bar(){
        Object a = new ArrayList<Integer>();
        ArrayList b = (ArrayList) a;
    }
}

Ausgabe:
