    ****************************************************************
    During Web Server plugin generation, OSGi applications
    component must contibute information for the plugin.  In order
    to do this it needs to iterate over all the applications
    installed, but it is only interested in OSGi applications
    rather than JEE applications.  There is no way for it to
    distinguish between the two types prior to reading the data
    from the disk which is slow.  If there are many JEE
    applications a significant overhead is incurred by reading JEE
    applications from disk when that data is of no interest to
    OSGi applications.
    

Problem conclusion

  • This APAR improves the performance of plugin generation by
    enabling OSGi applications to read only OSGi application data
    from disk.  If there are many JEE applications then this
    results in a significant performance improvement by
    eliminating the needless I/O overhead.
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 8.0.0.7 and the fix pack 8.5.5.1.
