Is there an easy to use C/C++ toolchain which targets the JVM? That may be the answer, because essentially that was what gave us WASM. Getting C/C++ code running in the browser was the motivation for Emscripten, and eventually this evolutionary branch gave us WASM (via asm.js). (and at the time there was plenty of competition: Adobe's Alchemy/Flascc which targeted Flash, and Google's (P)NaCl which compiled to native instructions and later (a subset of) LLVM bitcode, but notably, there was no similar attempt (that I know of) of a C/C++ compiler which targeted the JVM)
