How to access failure codes on event bus message replies?

[julian.or...@gmail.com]

While exchanging messages over the event bus, how can the requesting side get the failure code when the operation fails?. 

I need to map these failure codes to http error codes, right now I can only access the failure message with getMessage() or getLocalizedMessage().

I'm sure it must be obvious, but I just don't see it.

In most cases, the failure received by the client is an instance of https://vertx.io/docs/apidocs/io/vertx/core/eventbus/ReplyException.html

This object holds the failure code and type.
