Yes it occurs if you are trying to run pacmc with Java 16.

This is an issue with xodus-dnq, I have already created an issue there a while ago: JetBrains/xodus-dnq#75

For now I suggest to run pacmc with Java 11.

Im on manjaro linux with java 16

If you have installed multiple Java versions, you can switch between them like this:

Thanks, it works now with java 11

Fixed with version 0.2.0.

@mooziii for you that means that you can just update pacmc from the AUR
