Error description

• This APAR is an umbrella APAR for multiple fixes to the
  interaction between Enterprise Java Beans (EJB) and Contexts
  and Dependency Injection (CDI).
  
  1) Underlying EJB instances for CDI contextual references were
  not obtained by the container until they were dereferenced.
  
  2) Interceptors of stateless session beans are unnecessarily
  required to implement serializable.
  
  3) Under some circumstances, dependent-scoped EJB's injected
  into CDI beans did not get destroyed when the enclosing bean
  was destroyed.
  
  4) Under some circumstances, dependent-scoped
  managed beandependencies of an EJB are not destroyed when the
  EJB is destroyed.
  
  5) When an @Remove annotated method of a contextually injected
  stateful session bean is explicitly called, a required
  exception was not being thrown.
  
  6) EJB's without a no-interface local view (@LocalBean)
  could not specialize another managed bean.
  
  7) During contextual injection EJB initializer methods may
  result in [Object not instanceof declaring class]
  
  8) Disposer methods on an EJB may result in [Object
  not instanceof Class]

  This APAR is an umbrella APAR for multiple fixes to the
  interaction between Enterprise Java Beans (EJB) and Contexts
  and Dependency Injection (CDI).  Multiple problems related to
  injection via @EJB and @Inject annotations into both EJB's and
  CDI managed beans.
  

Problem conclusion

• The defects were resolved in the following manner:
  
  1) Underlying EJB instances for CDI contextual references are
  now created when the instance obtained (via Injection or
  BeanManager API)
  
  2) Interceptors of stateless session beans are no longer
  subject to being checked for implementing Serializable.
  
  3 and 4) Dependent beans of any type, injected into managed
  beans of any type, respect the lifecycle of their owning bean.
  
  5) When an @Remove annotated method of a contextually injected
  stateful session bean is explicitly called, an exception is
  thrown.
  
  6) EJB's can Specialize another bean without additional
  restriction.
  
  7) EJB initializer methods no longer result in an Exception.
  
  8) Disposer methods on an EJB no longer result in an Exception
  
  The fix for this APAR is currently targeted for inclusion
  in fix pack 8.0.0.1  Please refer to the Recommended Updates
