 * I have installed the latest closure compiler and set the paths correctly on W3
   Total Cache admin panel.
    Then I clicked on ‘Test’ and received the following
   error: Command (/usr/bin/java -jar ‘/usr/local/lib/compiler.jar’ ) execution 
   failed. Error: Error: Unable to access jarfile /usr/local/lib/compiler.jar . 
   Return code: 1.
 * How do I fix this?
