Last I checked there was a significant disadvantage to using rather basic Java JIT code in a cloud environment: slow startup time and poor initial performance in terms of requests per second & latency meant scaling on demand didn't work very well. I suggested we move to GraalVM and AOT compilation on that project but we just ended up over-provisioning by a significant factor to smooth things out.

The problem is friction. To run a rust app you can just run it. To run a java app you need to install java first. This is no problem for backends running on servers, but client apps (like Minecraft) have to include their own JVMs to reach a wider audience, and this solution still introduces a bunch of complexity.

Not a thing since Java 9 and jlink introduction, or since those commercial AOT compilers exist, for 20 years now.

And if free beer is your thing, GraalVM native image or OpenJ9 also produce a regular executable.
