    Description

      Java HotSpot(TM) Client VM warning: Performance bug: SystemDictionary lookup_count=21831450 lookup_length=1275207287 average=58.411479 load=5.572844

      I've never seen such warning before, and not sure that it relates to jvmci, but it happened in jvmci PIT, so targeting it to hs/compiler
