title: Emma is not creating the coverage.ec file
body: <p>Copied the emma.jar to <code>$JAVA_HOME/lib/ext</code> &amp; instrumented it using the following command.</p>
  
  <p><code>java -cp emma.jar emma instr -m overwrite -cp @jarlist.txt</code></p>
  
  <p>jarlist.txt contains the list of jar files deployed by tomcat from the war file. And it got instrumented successfully &amp; created the coverage.em</p>
  
  <blockquote>
    <blockquote>
      <p>EMMA: processing instrumentation path ...</p>
      
      <p>EMMA: instrumentation path processed in 5119 ms</p>
      
      <p>EMMA: [4125 class(es) instrumented, 3142 resource(s) copied]</p>
      
      <p>EMMA: metadata merged into [/root/install/apache-tomcat-7.0.19/webapps/coverage.em] {in 553 ms}</p>
    </blockquote>

  <p>But even after restarting the tomcat multiple times coverage.ec file was not created. What I'm missing here?</p>
