My point was not to this project in particular, but general. I have seen this reaction towards Java often. Java is not familiar, for many people Java is inscrutable. I think this is because of the existence of the JVM and the need for the user to be aware of its existence. Rust is not simpler than Java, but the user just deals with a compiled executable, he doesn't see any complexity. Maybe GraalVM with nativeimage will help Java in this regard.
