Regression: compiler accepts invalid cast from X[] to primitive array

      This program should be rejected:

      class Test<X> {
          Object o = (byte[])(X[])null;
      }

      Instead, the compiler accepts it, starting from JDK 7 b112. The problem is likely to be related to the changes in cats conversion involving 292 (see 6979683).
