  This APAR addresses the following issues with CDI:
  1) An IllegalStateException  caught when invoking an injected
  resource should be propogated to the caller.
  2) CDI should not proxy or subclass final classes.
  3) A zero argument initializer method throws a null pointer
  exception during CDI bean creation.
  4) Injected JPA EntityManagerFactory resources do not serialize
  and deserialize correctly.
  5) CDI beans cannot inject resources with the mappedName
  attribute.
  

Problem conclusion

• The following fixes were made:
  1) ResourceProxyHandler.invoke unwraps and throws the
  underlying cause of the InvocationTargetException.
  2) CDI container no longer proxies serializable resources
  injected into CDI beans. CDI should only proxy non serializable
  injected JEE resources.
  3) CDI container and the WebSphere Application Server Injection
  engine have been enhanced to support zero argument initalizer
  methods.
  4) CDI container and the WebSphere Application Server JPA
  container code has been modified to support correct
  behavior during serialization and deserialization of JPA
  EntityManagerFactory resources.
  5))CDI container and the WebSphere Application Server Injection
  engine have been modified to tolerate the presence of
  mappedName resource injections in CDI beans such as
  @Resource(mappedName="java:comp/BeanManager").
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.0.0.1.  Please refer to the Recommended Updates
