title: Understanding CPU time in visualvm profiler
body: <p>I have started to use visualvm for profiling my application which I launch in Eclipse. Then I launch visualvm which initially gives believable results. </p>

  <p>After some time two processes appear in the monitor which consume huge amounts of time. </p>

  <p>I have not deliberately invoked these. After a time they disappear. Are they an artefact of the profiling process and do I need to worry?</p>
  
  <p>Very few of my routines appear in the profile, mainly the libraries they call. Is there a way of showing which routines call the most heavily used ones?</p>
