Because that's how the people who invented Java made it...

If you need to return a return value to the operating system (so that you can use it in for example a batch file or shell script), use System.exit(n); to end your Java program (where n is the return code).

In C and C++, the return value of the main method can be used by the calling shell (e.g. bash). In Java, you use System.exit to give this value back to the calling shell.
 
It is sorta covered in the JavaRanch Style Guide.
