 *
 * @throws {@link TipOfSourceReferenceIsDifferentException} (client fault)
 *  <p>The tip of the source branch in the destination repository does not match the tip of the source branch specified in your request.
 *             The pull request might have been updated. Make sure that you have the latest changes.</p>
