JVM is a great choice! You might also want to check out WebAssembly too (full disclosure: I used to work on wasm). There aren't too many opcodes, and a lot of them are relatively simple math operations.

Once you get it working, you could run things like JSLinux! https://bellard.org/jslinux/vm.html?url=win2k.cfg&mem=192&gr...
