Major.minor version 51.0 correlates to Java version 7, which means that
somewhere in the pipeline Java 7 isn't being supported in your developer
environment.

Can you check your computer and see if you have any Java 6 or lower
installations (including SDK and runtimes)? If so, uninstall them and
adjust your OS environment variables to point to your Java 7 installation.
Also check to ensure you're running a recent version of the dev server.
