APAR status

  • Closed as program error.

Error description

  • An OSGi application may contain bundles that register and
    use OSGi services with an objectClass contained in an API
    package.  For example, javax.servlet.Servlet.  The Liberty
    runtime may also contain bundles that register OSGi services
    using the same objectClass.  Under certain circumstances it
    is possible for the OSGi application to get access to the
    OSGi services registered by Liberty runtime feature bundles
    whose objectClasses are from API packages but the services
    themselves are not considered APIs.

    ****************************************************************
    An OSGi application may contain bundles that register and use
    OSGi services with an objectClass contained in an API package.
    For example, javax.servlet.Servlet.  The Liberty runtime may
    also contain bundles that register OSGi services using the same
    objectClass.  Under certain circumstances it is possible for the
    OSGi application to get access to the OSGi services registered
    by Liberty runtime feature bundles whose objectClasses are from
    API packages but the services themselves are not considered
    APIs.
    

Problem conclusion

  • The Liberty feature header IBM-API-Service is used to specify
    which services are to be considered API services for use by OSGi
    applications.  In past releases this header did not strictly
    enforce access to service registrations.  Now this header is
    used to strictly enforce which services an OSGi application has
    access to at runtime.
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 8.5.5.9.  Please refer to the Recommended Updates page for
    delivery information:

Temporary fix

  • None.  Applications may be accessing OSGi services that are not
    considered API services.  With this fix applications will no
    longer be able to access OSGi services that are not considered
    API services.
