Problem conclusion

• HashMap was updated to a ConcurrentHashMap so that references
  can be released properly.
  
  NOTE: High heap usage is still expected, however, the
  ConcurrentHashMap should not be leaking.
  
  The fix for this APAR is targeted for inclusion in fix pack
  9.0.5.15. For more information, see 'Recommended Updates for
