Something in your application is getting compiled with your JDK 8
installation. You have to either remove the JDK 8 install, or reconfigure
your Eclipse installation/computer so JDK 8 isn't used. Try going into your
computer's environment variables and removing any reference to JDK 8.

The reason that JDK 8 is the culprit is that your stack trace declares a
unsupported major.minor version of 52.0. That version corresponds to JDK 8
(see this wiki page for
