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?

Hi Jonathan,

that's an interesting proposal. It is just unfortunate that a Java source file starting with "shebang" won't be a legal Java file according to the Java Language Specification. Or do you plan to change the JLS to allow (and ignore) "shebang" in the first line?

The program will be compiled and run, without the need to explicit invoke javac, or to package up a jar file.
