Thank you Christian for all the updates. Overall this looks good to me. I've added a few minor comments inline. I see that only compact source files are being tested in these new tests. Can you also add a regular source file with non-public static void main and verify that it works too?

Something like:


class FooBar {
     void main() {
     }
}
