I'm trying to render a diagram with the following code:

class diagram User {
    class MenuCategory {
        id:Long;name:String;

        1->1(MenuCategory); 
        1->*(MenuCategory); 
    }
}

The following exception is thrown:

org.modsl.core.util.ModSLException: Topological sort failed for
