 * I just installed the MMR plugin on my local MAMP installation to test it out 
   and now I keep receiving a Java Command Line prompt when visiting the website
   with the MMR plugin activated.
 * Example of the popup seen here: [https://discussions.apple.com/thread/7253814](https://discussions.apple.com/thread/7253814)
 * Any ideas why this would be? Thanks

 * MMR uses Google Closure to minify the Javascript. If it doesn’t detect the right
   version of java (or doesn’t have permission) then it falls back to using PHP 
   Minify. I’m guessing you don’t have Java installed so and its checking each time
   it needs to re-compile. I suggest either disabling minification (in plugin settings)
   or installing Java.

 * Thanks [@launchinteractive](https://wordpress.org/support/users/launchinteractive/)
 * Just checking, would the prompt also popup on the live website for those who 
   don’t have Java installed on their computer?

 * No it won’t. The end user doesn’t need JAVA. Its just the server/hosting.

 * Very cool, thanks [@launchinteractive](https://wordpress.org/support/users/launchinteractive/)
 * Would this plugin interfere with WP Super Cache?

 * No worries. I think it might have issues. I haven’t done any testing with WP 
   Super Cache. You might need to turn off some of its features to get it to work.
