gwt-dev and javax-validation:validation-api

Heya,

I'm using Dropwizard and GWT in the same project. Problem is, Dropwizard relies on javax-validation:validation-api 1.1.0.Final and GWT uses an older version of the lib.

With dependencyManagement, I've got the project to compile & run correctly. BUT, at test time, I get the following lovely error:

java.lang.IncompatibleClassChangeError: Implementing class

This happens when a class is being deserialized from Json by jackson, and that class uses a @Valid annotation.

I've tried all sorts of exclusions and dependencyManagements, changing scopes, etc but nothing worked, however if I take out gwt-dev, then it magically starts working.

Questions:

1) What's in gwt-dev which is causing validation-api to get included during tests (not at runtime) even when explicitly excluded?

2) It seems taking out gwt-dev causes SDM to not work, but other things continue working. Is it possible to exclude gwt-dev only for tests, but include it at dev time so SDM can work? (Right now, I've resorted to manually uncommenting gwt-dev when SDM needs to run but keeping it commented otherwise. Sooper hi tech)
