Description:
JLS Section 4.8 states that a generic inner class of a raw type can itself only be used as a raw type,it is not possible to access Inner as partially raw type (a "rare" type).But in the following code,cast to a partially raw type is allowed by the compiler. Compiler should instead be throwing an error.

<code>
bash-3.00$
<code>
bash-3.00$ cat Outer.java
<code>
class Outer<T>{
    
     class Inner<S>{
    }
     <R> void met(R r){
         
     }
     void met2(){
Outer.Inner oo2 = (Outer.Inner<String> )null; //Cast to partial raw type should not compile
// Outer.Inner<String> oo2 = null; // This does not compile on uncommenting, as expected.
Outer<String>.Inner<String> oo = null;
         this.met((Outer.Inner<String> )oo);//Cast to partial raw type should not compile
     }
    
              
}
</code>
Compiles fine. Compiler should actually be throwing an error as the cast type is illegal.
