I have not once seen a Java application that shipped as a native binary. Sure, it can be done, but this is a very rare experience practice.
I have seen plenty on the enterprise, done by companies that actually pay for their tools, or do deployments into embedded targets.
Also Android J++ does AOT compilation, as sidenote.
Now that OpenJDK is starting to offer AOT compilation for free, maybe there will be more adoption among FOSS crowd.
So when is Electron going to support the same features?
