Kotlin just needs to be rebuilt with OpenJDK 17 to pick the Java 25 
fixes in intellij-community-idea/183.5153.4-7, so this issue is likely 
to be fixed.

That said, relying on Kotlin to build a font remains a risk, I think it 
would be wise to rewrite the fonts-jetbrains-mono's Kotlin script in 
pure Java [1], any LLM should be able do that in a second.
