Sandboxing and security

Running Mobility-RPC isn't safe anywhere except a tightly controlled network, because it will literally let anyone send you arbitrary code to execute, without any authentication or security at all. Thus...

Using CompletableFuture would simplify the code and be more powerful for users

It'd be great if there were async versions of execute. It looks easy to add: just replace FutureExecutionResponse with a real CompletableFuture, return it from the execute methods and then...

Java generated fromFile(String) method leaks file handles
