A developer creates a stateful session bean that is used by many concurrent clients. The clients are written by other development teams and it is assumed that these clients might not remove the bean when ending their session. The number of concurrent sessions will be greater than the defined bean cache size. The developer must consider that the state of the session bean can be influenced by either passivation or timeout. Which three actions should the developer take to make the bean behave correctly in passivation and timeout situations? (Choose three.)

A. Release references to resources ina@Removeannotated method.

B. Re-establish references to resources in an @lnit annotated method.

C. Release references to resources ina@PreDestroy annotated method.

D. Release references to resources in a @PrePassivate annotated method.
