Spring Boot support for Cloudlinux
The Spring Framework has convention-over-configuration rapid application development similar to NodeJS/Rubygems named Spring Boot.
It's basically works in a similar way that Node works to run standalone web applications but it's java based allowing standalone applications running as a service without the need to install and configure a tomcat or similar application server, running everything embeded in the application execution and able to be integrated to a webserver via Passenger.
Due the CL already have the full support for Passenger integration with Node, you may able to add support to Spring Boot to jusk making some modifications.
