It appears Java 8 has tightened up rules on casting. To fix some of the problems:

Prefer calling superclass methods to accessing the protected instance variables. For example:

   short x, y, z;
   x =;
   y =;
   z = (short) x + y;

In dump, trying to output members of the elements array can cause casting errors at runtime. A simple workaround is

Object[] elementsCopy = elements;
for (int i = 0; i < topIndex; i++) {
   System.out.println((Short) elementsCopy[i]);
