org.apache.commons.pool.ObjectPool.addObject()
Create an object using my {@link #setFactory factory} or otherimplementation dependent mechanism, and place it into the pool. addObject() is useful for "pre-loading" a pool with idle objects. (Optional operation).

        pool = new StackObjectPool(factory, 1, 2);

        pool.addObject();
        assertEquals(1, pool.getNumIdle());
    }
