For users of the Hibernate native APIs, we've had to rename this method as defined by Hibernate historically because the JPA contract defines a method of the same name, but returning the JPA FlushModeType rather than Hibernate's FlushMode .

 * @param allowStale <code>true</code> to allow stale copies of an alert
