/**
 * Borrow an object from the pool using the specific waiting time which only
 * applies if {@link #getBlockWhenExhausted()} is true.
 * <p>/*from w  w  w .  j  ava 2s . c  o  m*/
 * If there is one or more idle instance available in the pool, then an
 * idle instance will be selected based on the value of {@link #getLifo()},
 * activated and returned. If activation fails, or {@link #getTestOnBorrow()
 * testOnBorrow} is set to <code>true</code> and validation fails, the
 * instance is destroyed and the next available instance is examined. This
 * continues until either a valid instance is returned or there are no more
 * idle instances available.
 * <p>
 * If there are no idle instances available in the pool, behavior depends on
 * the {@link #getMaxTotal() maxTotal}, (if applicable)
 * {@link #getBlockWhenExhausted()} and the value passed in to the
 * <code>borrowMaxWaitMillis</code> parameter. If the number of instances
 * checked out from the pool is less than <code>maxTotal,</code> a new
 * instance is created, activated and (if applicable) validated and returned
 * to the caller. If validation fails, a <code>NoSuchElementException</code>
 * is thrown.
 * <p>
 * If the pool is exhausted (no available idle instances and no capacity to
 * create new ones), this method will either block (if
 * {@link #getBlockWhenExhausted()} is true) or throw a
 * <code>NoSuchElementException</code> (if
 * {@link #getBlockWhenExhausted()} is false). The length of time that this
 * method will block when {@link #getBlockWhenExhausted()} is true is
 * determined by the value passed in to the <code>borrowMaxWaitMillis</code>
 * parameter.
 * <p>
 * When the pool is exhausted, multiple calling threads may be
 * simultaneously blocked waiting for instances to become available. A
 * "fairness" algorithm has been implemented to ensure that threads receive
 * available instances in request arrival order.
 *
 * @param borrowMaxWaitMillis The time to wait in milliseconds for an object
 *                            to become available
 *
 * @return object instance from the pool
 *
 * @throws NoSuchElementException if an instance cannot be returned
 *
 * @throws Exception if an object instance cannot be returned due to an
 *                   error
