Powermock and Dropwizard?

[Panagiotis Partheniadis]

Hello everyone,

I'm trying to use Powermock in order to stab a final method of a mock. Nevertheless, when i try to annotate the Resource Class with the @RunWith(PowerMockRunner.class) annotation, the PowerMockRunner fails to run with the following exception:

javax.validation.ValidationException: Unable to get available provider resolvers.

Anyone knows something about this?

I am seeing this issue also.

did you find a resolution ?

Is that the full stack-trace? Have you omitted any "Caused by:" sections?

Looks like a ClassCastException:
