I've run into this issue a couple times, where we'll pass around a pre-built jar and different environments act differently by default. As it stands now, the responsibility lies on me to always remember when using docker java to pass -Dfile.encoding=UTF8 (and it's probably good practice anyways). But again... whenever a bug like this pops up it takes me a couple hours to figure out what's going on and that's never fun. Should the docker java image have UTF8 by default?
