EJB 1.1 Spec (9.1.5.2):
The exact times that the container invokes ejbLoad depend on the
configuration of the component and the container, and are not defined by the
EJB architecture. Typically, the container will call ejbLoad before the
first business method within a transaction to ensure that the instance can
refresh its cached state of the entity object from the database. After the
first ejbLoad within a transaction, the container is not required to
recognize that the state of the entity object in the database has been
changed by another transaction, and it is not required to notify the
instance of this change via another ejbLoad call.
