So if I am correct the answer to Question 2 is: Yes, behavior must be the same.
What are the next steps to take for this? And can someone also answer my
Question 1: Where can I find the tests for these changes?
Question 2: Where should the common code for this be located?
Question 3: Is it an idea to first implement below patch and backport
that, and in addition as new ticket implement the new behaviour also
Question 4:Is this they way to do it, or is there a better way to
provide debug information to users running javac?
