  14  * Base class for all exceptions occurring during data change actions within the service layer.
  15  * NOTE: This exception needs to be thrown before any data is saved to the session as it rather forces
  16  * commit then rollback. This is intended behavior to avoid full transaction rollback within longer
  17  * transactions. This way we do not need an explicit method to check if a data change method will
  18  * succeed or fail.<BR>
  19  * To avoid rollback the class on purpose does not inherit from RuntimeException
  20  * as RuntimeException leads to rollback when using {@link DefaultTransactionAttribute#rollbackOn(Throwable)}
  21  * which is used by spring as default transaction attribute.
