Interpreter is slow, you need to run native. There is wasmer java, which is JNI binding to wasmer runtime.

Then graal has wasm support, but you need graal, not just any JVM (you can also run in stock JVM, but only in interpreted mode with som graal libs, but this mode is not supported).

And both of these are ok-ish for pure functions. If you need callbacks to your host (typically needed for plugins) you are screwed.
