It seems that this is probablyt a known issue:

This happens when you generate the codegen with Java 17 instead of 11 and then you run npm run build on one of the samples.`

To verify this I used Java SDK 11 and rebuilt my own copy of codegen and it works on Windows. So this known issue seems to be a valid thing.

Is there any estimate / idea when that known issue would be fixed?

Not entirely sure I follow.

The codegen is a native executable (using GraalVM) not using any local Java installation, are you saying you rebuilt an image of your own but based on a different GraalVM version than 22.1.0, or that you built the codegen Java library with JDK 17 first and then generated a new native image with the default GraalVM?
