Suspicious array cast

Reports suspicious array casts. An array cast is considered suspicious when it casts to a more specific array type. Such a cast is legal at compile time but may fail with a ClassCastException at runtime.

Example:

  Number[] numbers = new Number[]{1L, 2L, 4L};
  Long[] longs = (Long[])numbers;
