Re: javax.validation.constraints.NotEmpty Exception

Hi,

did you add the correct ConfigurationSourceProvider in your initialize() method as described in [1]?

Also, the pattern "${aws:/prod/username:-root}" looks weird. What do you want to achieve with it?

Cheers,

Jochen

Hi,

I am using dropwizard version 2.0.10 and a custom DefaultConfigurationFactoryFactory.

I am able to replace the properties with the correct once in the initialize method, but when calling the run method, I am getting following exception:
