Congratulations on a great product! I've played with it quite a bit and we finally have a great version of Java in the browser!

One missing feature is the native code support for JNI.. Currently you have to manually provide JS functions to CheerpJ, and this isn't integrated with CheerpX AFAIK

As part of the next release cycle we plan to release our C/C++ JNI implementation so that 3rd party JNI components can be compiled to dynamically loaded .wasm libraries.

This will be based on Cheerp (our C++ -> WebAssembly compiler).

Integration with CheerpX is another possibility, but we think building the modules from source it's a more realistic solution in the medium term.

Not using the system's runtime also means that it's impossible for an applet to attatch to a local java process as a debugger.
