We can already run arm seamlessly on x86 Linux, why not use Qemu-user + binfmt misc the other way around? I guess FEX must be much faster. Im also not super keen to run binaries that can't be recompiled anyway so probably not the target audience.
Take that Java, everything is a portable binary now.
I hate Java with the white hot passion of a thousand suns. It is baked into so many admin tools for hardware (Dell, Cisco, etc) and trying to connect to older hardware that requires a security model that isn’t supported anymore or has expired certs that are never getting updated is a giant pain in the ass. Run anywhere my ass. I have to keep special VMs with just the right version of Java and all the necessary tweaks (like having to tell it that certain older encryption methods are ok) to even access some of these tools. I’ve even had to surplus hardware that was perfectly fine accept for the fact I could configure it because of some stupid Java thing. In short Fuck Java with a rusty wire brush.
