             installUtility uninstall zosBundle
    
    the following error occurs:
    
            CWWK1436E: One or more features cannot be uninstalled:

            Comparison method violates its general contract!
    

Problem conclusion

  • Although the command failed, the zoBundle addon and most of its
    features should be uninstalled.
    
    Code has been corrected so that no error will occur.
    
    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
    delivery information:
    http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980
    

Temporary fix

  • We recommend that customers not attempt to uninstall the
    zosBundle add-on at the fix pack 8.5.5.7 level.
    
    If they do choose to uninstall zosBundle, use java6 or java8. If
    using java7, they must execute the following before uninstalling
    zosBundle:
    	export JVM_ARGS=-Djava.util.Arrays.useLegacyMergeSort=true
    
    If zosBundle is uninstalled, some zos features cannot be
    reinstalled. You may need to uninstall the Liberty offering and
    reinstall it.
