282 throw new RuntimeException(module + " does not have
main class: " + mainClassName);
- Throwing IllegalArgumentException would probably be better.
101 err.launcher.value.format:launcher value should be of form
<command>=<module>: {0}
- should this message include optional main class; something like
<command>=<module>[/<main-class>]
This validation is done after the image is created. Can you file a JBS issue
to separate the launcher file creation and the validation from image creation?
That can be improved in the future.
Otherwise, looks okay. No need to send a new webrev.

P.S. There is some issue to access cr.openjdk.java.net. I got a copy of
webrev.02 from Sundar to review.
