You're intended to use it like this: either you distribute JARs and the recipient triggers the AOT compilation if they want it, or you distribute a "jlinked" JRE image that's inherently OS specific because it includes a bundled JVM. It's also possible that a future Java module format will allow the AOT compiled code images to come along for the ride next to the classfiles.
There are other JVMs that already do AOT compilation. This just brings an AOT compilation option to Java. It also looks like the contained file will include both the compiled version and the normal bytecode, so that the code can be recompiled if/when necessary.
