title: Can't load javaagent
body: <p>On <em>Ubuntu 14.04 x64</em>, getting this error</p>
  
  <pre><code>Picked up JAVA_TOOL_OPTIONS: -javaagent:/usr/share/java/jayatanaag.jar 
  Error opening zip file or JAR manifest missing : /usr/share/java/jayatanaag.jar 
  Error occurred during initialization of VM agent library failed to init: instrument
  </code></pre>
  
  <p>Therefore, I can't load any java app. Tried to reinstall <em>java</em>, still doesn't work. </p>
  
  <p>Could it be corrupted <em>jar</em> from ppa repo?</p>
  
  <p>How to fix this?</p>
