Such a > situation could be described as bad user experience and we should fix > it. Var handles [2] could be used for solving described problems. > > * Java 9+ introduces Flight Recorder API [3] which could be used in > the Ignite project for lightweight profiling of internal processes. > > Please, share your opinions, objections and ideas about this topic.
