The compiler reports that field x of inner class B is never used locally, although it is in fact used by the enclosing class A.  No warning is reported against field x of inner class C, but B and C are nearly identical except for the use of generics in B.

    public class A
    {
      private static class B<T>
      {
        private Object x;
        
        public B(T x)
        {
          this.x = x;
        }
      }
    
      private static class C
      {
        private Object x;
    
        public C(Object x)
        {
          this.x = x;
        }
      }
    
      public static void main(String[] args) throws Throwable
      {
        B<String> b = new B<String>("foo");
        System.out.println(b.x);
    
        C c = new C("foo");
        System.out.println(c.x);
      }
    }
