title: Symfony 2: MemcachePool not found
body: <p>I was upgrading my Symfony 2 project, which works with the lws_memcache Bundle.</p>
  
  <p>Now my I get the following error:</p>
  
  <blockquote>
    <p>ClassNotFoundException in LoggingMemcache.php line 4: 
    Attempted to load class "MemcachePool" from the global namespace.
    Did you forget a "use" statement?</p>
  </blockquote>
  
  <p>The File lies in the vendor of the lws_memcache Bundle, so I can't change the code.</p>
  
  <p>My memcached Server is on the version 1.4.14, the bundle itself is the newest verison.</p>
  
  <p>This is what my IDE (PHPStorm 8) shows me when I hover over the Class <code>\MemcachePool</code> in the vendor code.</p>
  
  <blockquote>
    <p>Multiple definitions exist for class MemcachePool less... (Strg+F1) </p>
    
    <p>Undefined class: Declaration of referenced class is not found in
    built-in library and project files. Multiple declarations: this
    version of IDE <em>will</em> have problems with completion, member resolution
    and inheritance analysis for all classes that have multiple
    definitions in project files (regardless of includes).</p>
  </blockquote>
  
  <p>Is there something I can do about it?</p>
