Question:
The bean developer must be cautious when iterating over a relationship collection class, because:

The container of EJB 2.0 is not required to support the collection classes


The collection can be modified by another EJB


Concurrent transactions can modify the values


Changes to its contents can violate foreign key constraints in the database


The collection contains remote interfaces to EJBs that are temporary deactivated by application server.


Changes to its contents can trigger a referential integrity change to
the collection class itself
