java.lang.NoClassDefFoundError: Could not initialize class
play.data.format.Formatters

I'm using Play 2.1.2 and I want to use dynamic forms. I tried it in my own
small hello world project and everything worked fine, but when I use forms
in other bigger project I'm getting an exception. Here is my code (in both
project is the same):
Controller
public static Result signInForm() {
DynamicForm form = Form.form().bindFromRequest(); //exception on
this line
return renderJapid(form);
}
Routes
GET /sign-in
controllers.Authentication.signInForm()
When I go to localhost:9000/sign-in I get this exception:

Please, can you help me? Where could be the problem? I've checked
Global.java and application.conf in both projects but I didn't find
anything what could cause this problem.
