Note that I did an edit in the stack trace above, replacing the reference to the line in my class which you cannot see, to the code executing on that line which is a call to ClassLoader.findClass(name). Probably not relevant, but just in case.

As usual in Jira you are either in hell or in heaven but never on earth, so setting priority is hard. I left it at Major since as I understand it, this is something that will fail rather than warn in JDK 12.
