Problem summary

    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server Liberty Profile - Contexts and       *
    *                  Dependency Injection (CDI)                  *
    ****************************************************************
    * PROBLEM DESCRIPTION: An application with a large number of   *
    *                      jar files that used to work on cdi 1.0  *
    *                      might experience slow startup if cdi-   *
    *                      1.2 feature is enabled.                 *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    In CDI 1.0, if an archive does not have a beans.xml then CDI
    ignores it completely. In CDI 1.2, it is no longer true and that
    can have a negative impact on startup performance, particularly
    for large applications which do not use CDI.
    

Problem conclusion

  • To match the CDI 1.0 performance and behaviour, the archives
    that do not have a beans.xml file will be ignored if the setting
    <cdi12 enableImplicitBeanArchives="false"/> is specified in the
    server.xml. This is only intended to be used when deploying old
    CDI 1.0 applications on cdi 1.2 feature and do not wish to use
    implicit bean archives.
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 8.5.5.8.  Please refer to the Recommended Updates page for
