Using GraalVM to run Java on Heroku

Is there any ability to use GraalVM to run Java apps on Heroku? I read a lot articles about cold starts of Java applications with GraalVM AOT (ahead-of-time) compilation feature and how it decrease startup time and I'd like to try to use it in my projects deployed on Heroku.

This buildpack can be used with the Heroku Java buildpack to replace the default JDK with Graal by running:

$ heroku buildpacks:set https://github.com/jkutner/graal-buildpack
$ heroku buildpacks:add heroku/java
