Hi Mukesh,

There exist Iris formalizations of (subsets of) at least Rust, Go, OCaml and 
WebAssembly, and an axiomatization of C++. There is a Scala type soundness proof 
in Iris but I don't think it comes with a separation logic that can be used to 
reason about imperative Scala. I'm not familiar with any work specifically on 
Java, unfortunately.

Kind regards,
Ralf
