So yes, module and its console implementation is 1:1, which is reflected by the system property `jdk.console` that takes the module name. So that `break;` effectively shortcut the unnecessary looping (I don't think it would happen btw). That said, I think it needs to be described in the comment above that piece of code. I will add it shortly. ------------- PR Review Comment: https://git.openjdk.org/jdk/pull/19467#discussion_r1621231072
