If an entity id is present in the search index but not in the database, this exception bubbles up to the top and the app crashes:

Caused by: javax.persistence.EntityNotFoundException: Unable to find org.jboss.seam.wiki.core.model.WikiDocument with id 1330

The code in ObjectLoader.java is supposed to prevent this but it only catches org.hibernate.ObjectNotFoundException.
