When online_mode is false, I can't connect because of I'm a not whitelisted user

[RickPijnenburg]

When I start the container with the following command, I can't connect to the minecraft server, even when I'm in the whitelist.json file.
docker run -d -v /minecraft-data:/data -e TYPE=BUKKIT -p 25565:25565 -e EULA=TRUE -e ONLINE_MODE=FALSE -e WHITELIST=xxxxx --name Minecraft_Java_Server itzg/minecraft-server

When online_mode is true, I can connect. Then it doesn't mather if I was whitelisted or not.

It seems when online_mode is false, the whitelist.json is not working. When whitelist is off, then I can join. When whitelist is on, I can't join.
Other setting in server.properties is working.

I found something helpfull.
When starting the container with the whitelist option on and add yourself to it, it gets the UUID of your online account.
But when ONLINEMODE=FALSE you get another UUID. So after the server is up and running, you have to go to the console and add yourself to the whitelist or ops-list. When you do so you can join the server with the OFFLINE UUID account.
When you want to add someone else, you have to disable the whitelist, let the person join, then add the person to the whitelist in the console and turn on the whitelist.
