Problem summary

  • ****************************************************************
    * USERS AFFECTED:  IBM WebSphere Application Server            *
    *                  9.0 and Liberty users of JavaServer Pages   *
    *                  (JSP) 2.3 and Expression Language (EL)      *
    *                  3.0.                                        *
    ****************************************************************
    * PROBLEM DESCRIPTION: JSP 2.3 applications using EL 3.0       *
    *                      unscoped or static values may see       *
    *                      longer page load times.                 *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    By optimizing EL 3.0 context handling and classloader calls,
    the evaluations of EL unscoped and static expressions perform
    better with this fix.  This is a port of Apache bug fix 62453.
    The issue was previously described in informational APAR
    PI92335 and relates to the specification changes in EL 3.0
    that expand the supported evaluation types.
    

Problem conclusion

  • EL performance is improved for unscoped and static values.
    The fix for this APAR is targeted for version 9.0.5.7 and
    21.0.0.2.  For more information, see 'Recommended Updates for
    WebSphere Application Server':
