  ****************************************************************
  In Websphere Liberty versions 20.0.0.7 through 20.0.0.11 there
  is a problem with communications between the JVM supplied Health
  Center function and the Liberty healthAnalzyer feature.  This
  problem prevents the healthAnalyzer feature from gathering heap
  statistics.  These statistics are vital to its ability to
  trigger the memory leak and memory usage conditions.
  

Problem conclusion

• The healthAnalzyer feature has been modified to use the health
  center's updated interface.  The health center feature is only
  available at this time on IBM originated JVMs.
  
  The fix for this APAR is currently targeted for inclusion in fix
  pack 20.0.0.12.  Please refer to the Recommended Updates page

Temporary fix

• There is no work around for this issue other than avoiding the
  use of the affected fix packs.
