This is pretty exciting. I have tried to build a native image using GraalVM for Jenkins as mentioned in this article and it was not possible due to Jenkins relying on reflection. Hopefully this helps with resource usage, I always feel a bit of OCD with Java applications tending to require tons of resources and developers being okay with it. Sure, companies have more money to spend and can afford larger instances but it takes away some of the spirit of hobby, DIY, and projects outside of work.
This should also mean that you can build Jython and JRuby static binaries/executables, but it will probably be a large binary.
