Okay so for making the reload respect only already loaded files, then we
can match the "changed file event" form the JDK
and match if it was previously loaded or not. And then skip it if not.
Then users can turn this on via some new option (maybe name it only
existing files, or some better name? ).
withRoutesReloadOnlyExistingFiles(true)
You are welcome to create a JIRA ticket for that.
