title: How to disable Tern synchronization in Eclipse Luna?
body: <p>I use Eclipse Luna SP2 for Java EE for some JavaScript development.
  Every now and then (mostly on .js file open but also on some timer) I get the following popup error </p>
  
  <pre><code>    An internal error occurred during: "Synchronizing script resources with Tern server...".
      loader constraint violation: loader (instance of org/eclipse/osgi/internal/loader/EquinoxClassLoader) 
  previously initiated loading for a different type with name "org/apache/http/HttpEntity"
  </code></pre>
  
  <p>I don't need Tern functionality and I would like to disable it or at least get rid of the popup error</p>
  
  <p>I googled about but could not find any relevant information.
  For the moment I tried to disable all validators and to change the .js editor but no luck by now.</p>
  
  <p>Any idea?</p>
