     * add succeeds if not full; throws ISE if full
     */
public void testAdd() {
    ArrayBlockingQueue q = new ArrayBlockingQueue(SIZE);
    for (int i = 0; i < SIZE; ++i) {
        assertTrue(q.add(new Integer(i)));
    }
    assertEquals(0, q.remainingCapacity());
    try {
        q.add(new Integer(SIZE));
        shouldThrow();
    } catch (IllegalStateException success) {
    }
}
