Why this has to be implemented in C++ (ie. why not Java?)

Because we have currently no way to register and use mojo service in java in the
shell itself. As this is currently the only usage, I won't setup the full needed
infrastructure. As suggested, I opened a bug, and we can go back to this when
needed.

could you indicate the interface we're overriding in a comment?

Done.
