New candidate JEP: 458: Launch Multi-File Source-Code Programs

[Mark Reinhold]

  Summary: Enhance the java application launcher to be able to run a
  program supplied as multiple files of Java source code. This will
  make the transition from small programs to larger ones more gradual,
  enabling developers to choose whether and when to go to the trouble of
  configuring a build tool.
