Examples of javax.persistence.NonUniqueResultException

javax.persistence.NonUniqueResultException
Thrown by the persistence provider when getSingleResult() is executed on a query and there is more than one result from the query. This exception will not cause the current transaction, if one is active, to be marked for roll back. @author Gavin King
