[Bug] javac gives non-deterministic output (for sealed interface with records)

[Przemek Bielicki]

Probably - I don’t have the environment and I also never built the JDK from
sources it I have a technical skills to eventually do it 😉

Can you pls point me to some docs on how to build the JDK from scratch?

Cheers,
Przemek
