Exception when executing method :java.lang.NoClassDefFoundError

Question

When i run http://localhost:8080/domain/account, it returns a ava.lang.NoClassDefFoundError: Could not initialize class org.eclipse.persistence.jaxb.BeanValidationHelper

When i remove the parameter User in the createUser method, it runs successfully. am i missing a pom dependency?

import com.domain.model.User;

@Path("account")
public class AccountController {

  @PermitAll
  @POST
  @Produces({"application/json"})
  public Response createUser(User user) {
    return Response.ok("asasd").build();
  }
}
