You're right that the fundamental ideas behind WebAssembly and WASI are not particularly new.

The most exciting part about WASI for me, though, is that it's sticking to a capability-based interface and it's actually gaining a lot of traction. There are few examples of capability systems getting as much attention as this.

Do you have any pointers to more in-depth comparisons to Java's security model and some analysis of why wasm should work better?

Is the idea mainly that permissions are more fine-grained? It probably makes porting existing applications tricky, though, right?
