There are some examples of toolbox tests in  `jdk/test/langtools/tools/javac/modules` though I don't have a good example of one that verifies the contents of the class file. Perhaps @vicente-romero-oracle can point to an example?

Hi @lgxbslgx 

This looks good to me. Since this is targeted to Java 16 we need to close this PR and open a new PR towards the JDK16 project and finish the review there, add a link back to this PR would also be neat. Can you do that?
