<p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">In addition to the behavior for PessimisticLockScope.NORMAL, element collections and relationships owned by the entity that are contained in join tables will be locked if the javax.persistence.lock.scope property is specified with a value of PessimisticLockScope.EXTENDED. The state of entities referenced by such relationships will not be locked (unless those entities are explicitly locked). Locking such a relationship or element collection generally locks only the rows in the join table or collection table for that relationship or collection.
