Draft JEP: Launch Single-File Source-Code Programs

[Robert Zenz]

I fail to see why a shebang would be required at all for this proposal, can't
`java` figure out that it was handed a source code file (ends with .java and is
not a class file or jar)? Or alternately provide a switch to run source files?
