  pack 8.5.5.8.  Please refer to the Recommended Updates page for

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.
