If you're using RPC, then you should make sure that your server will only throw exceptions that are declared in the throws cause of the service interface method (or exceptions that are a subtype of whatever is declared).
This means catching exceptions server-side and re-throwing an appropriate exception, as well as making sure there's a throws clause on your service interface methods.
