Slightly off topic. And I may be getting ahead of things.

Do Oracle allow one to package only the necessary JVM parts into another distribution? i.e JRuby + Truffle + Graal without other unnecessary Java bits?

This is looking like the most promising Ruby implementation.

No, the JVM is not built for that. Jigsaw sound like what you want:

Its totally experimental and they call it a substrate vm. You can see references to them on some graal truffle slides. These have startup performance in the same ball park as mri ruby. project jigsaw is a project to make the java vm start faster by splitting the big rt.jar in many. The rt.jar is where all the standard java claasses are stored. Benefits better security and control
