title: Tool to extract java stack traces from log files
body: <p>Is there any tool that can extract a list of stack traces appearing in the log file and probably count unique ones? </p>
  
  <p><em>EDIT</em>: I would preffer something that is not GUI-based and be run on the background and give some kind of report back. I have quite many logs gathered from several environments and just would like to get quick overview.</p>
