Hi, We've gotten feedback from the developers that it is currently difficult to retrieve the reason field from the ApiError since in statically typed languages you must first cast the error. I think the reflection tactic you've outlined in version 2 is a good work around for this problem. If you are using the AdWords API Java client library there is currently a feature request open that you can comment on:
