I think you shouldn't compare Rust to Java (the language), you should compare it to Java (the ecosystem). The JVM is rock solid and very performant, and you have languages like Java++ (called Kotlin) and Haskell# (called Scala), or even Common Scheme (called Clojure). The same is true for the ecosystem, eg. build tools (Maven/Gradle are the default ones, but there are many more), frameworks (Spring + all the reactive stuff), the largest number of libraries on the planet after C, and so on.

The target niche is not exactly the same though, you wouldn't want to systems program on the JVM, and it would probably not make much sense to choose Rust over Spring Boot for web programming. YMMV of course.
