This doesn't exist in jython (or python for that matter) variables have no 
type checking so there is no sense to try to cast. In you case the obj 
variable is of type Obj2 and therefore of type Obj1 too. If you have a metho 
aMethod() in Obj1 you can call it as

obj.aMethod() without need to cast, the same goes for variables
