Server Liberty Profile - Install V8 and
above

PROBLEM DESCRIPTION:
Rollback fails from Liberty 8.5.5.7 to
8.5.5.3 and below

RECOMMENDATION:
None

This was caused by missing setClassPath call from offering SU.
When performing a Rollback, it requires an invoke of
installKernel to uninstall archive runtime assets by SU.
However, it failed because the required classpath was missing.

PROBLEM CONCLUSION:
Added the required setClassPath call in offering SU.

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
