The protocol is dead simple. The browser sends JBOX_PING through the terminal. CompileServer responds with JBOX_PONG. That’s how the SDK knows the JVM is alive. Then to compile and run, it sends JBOX_COMPILE ClassName followed by the source code followed by JBOX_END. CompileServer compiles, runs, prints the output, and finishes with JBOX_EXIT:0 (or whatever the exit code was). The whole thing uses BufferedReader because anything fancier (like JLine) breaks after snapshot restore.
Semantic predicates: Turing-complete code, such as building a type table. Technically speaking, the first two are just simpler cases of this, but I want to emphasize their simplicity. You could also move in the other direction, toward a far more complex solution, especially if the language is poorly designed.
