Is launching *any* Java program specified SE even if you do know the name of its main class?

For example, JLS §12.1.4 specifies the `main` method but doesn’t specify how the main class is launched. Does it matter, then, that the chosen name for the main class is implementation-specific given that launching the main class is also implementation-specific?

Perhaps the best way to test implicit classes, then, is from *within* the implicit class itself. Like any other main class, it is launched by some implementation-specific mechanism, but once you’re in it, everything is known. You can then get the chosen class name with `this.getClass()…`.
