title: Play Framework: EhCache issue on every code hot compile
body: <p>In Play 2.5.3, using Scala:</p>
  
  <p>I'm using cache as a module, and every time I change the code and then refresh my browser, after the recompile I am getting the following issue:</p>
  
  <pre><code>[TechnicalException: com.google.inject.ProvisionException: Unable to provision, see the following errors:
  
  1) Error in custom provider, play.api.cache.EhCacheExistsException: An EhCache instance with name 'play' already exists.
  
  This usually indicates that multiple instances of a dependent component (e.g. a Play application) have been started at the same time.

  <p>I am using cache (a named one, not the default <code>play</code>) for a few actors. How could I solve this issue?</p>
  
  <p>Thanks!</p>
