      Description

      The following program crashes the compiler if compiled with -Xlint:unchecked

      class Test {
         Object o = new Object() {
         <Z> void m (Class<Z> x) {}
         void test() {
            m((Class)null);
         }
         };
      }

      Here's the stack-trace:
