Sever Property file generation seems to be incorrectly escaping special characters

[alexchomiak]

When configuring my docker-compose configuration with the following environment property:

LEVEL_TYPE: 'gardenofglass:gardenofglass.'

The generated server.properties file sets the level-type value as follows:
level-type=gardenofglass\:gardenofglass.

It seems to be escaping the semicolon, but not removing the forward slash /.

This is causing world generation to behave incorrectly. Trying to manually correct the value just has this overwritten with the correct one. (even if omitting the environment variable)

That is standard java properties file behavior:

Minecraft wiki also states that colon must be escaped:

Are you sure that trailing period isn't the problem?
