title: How to analyze information from a Java core dump?
body: <p>If a process crashes and leaves a core dump or I create one with <code>gcore</code> then how can I analyze it? </p>
  
  <p>I'd like to be able to use <code>jmap</code>, <code>jstack</code>, <code>jstat</code> etc and also to see values of all variables. </p>
  
  <p>This way I can find the reasons for a crashed or frozen JVM.</p>
