[okadakenichi]

Portablemc cannot comprehend the path stype of MSYS2 such as "C:/Users/username/...".

Thanks for the report! It seems that the version of java running is a Linux one, is it possible? I don't understand why log4j can't understand a windows-style path for the configuration... Could you check that?

However this doesn't explain why portablemc is building windows-style path but at the same time is using a Linux JVM

[okadakenichi]

I use Windows JVM due to the native library of LWJGL.

Python under MSYS2 environment converts path, and somewhere is wrong along the path conversion.

I put this in triage because I first need to reproduce it on my side to get a better understanding...
