@kmdrGroch please don't forget about log4js-node/log4js-node#1037

This was the reason for me not to migrate earlier. If I recall correctly, the Linux pipelines will fail.

that is indeed strange :/ I didn't know there was such an issue out there

Yeah, we'll need to investigate. We're probably doing something undocumented that isn't supported anymore. For example, we're calling log4js.configure multiple times, that's probably shady territory.

The log4js configuration was complicated because of the old ConfigEditor plugins. They had the ability to change the logLevel. This is why we choose to call log4js.configure a second time after loading them. Since those plugins are no longer supported (I love v4 🎉), we might be able to simplify the log4js configuration.

@nicojs You will be able to call log4js.configure() multiple times from log4js@6.4.0 onwards.
