    Description

      There are occasions when some insight into the current state of the JVM code heap would be helpful to answer questions like
       * Why is the JIT turned off and then on again and again?
       * Where has all the code heap space gone?
       * Why is the method sweeper not working effectively?

      Implement an on-the-fly analysis of the code heap. Trigger analysis and output via command-line parameter (state when vm shuts down) and via jcmd (at any time).
