[keycloak-user] AdapterDeploymentContextBean no default constructor

I'm working on kyecloak 1.7.0 final.I'm trying to integrate a new spring secured web application with keycloak sso mechanism.Following the last guide reference, specifically the chapter 8.10 i wrote a keycloak-security-context.xml containing the specified configuration.When i deploy application i get this error: Caused by: org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.keycloak.adapters.springsecurity.AdapterDeploymentContextBean]: No default constructor found; nested exception is java.lang.NoSuchMethodException: org.keycloak.adapters.springsecurity.AdapterDeploymentContextBean.<init>() Effectively AdapterDeploymentContextBean https://github.com/keycloak/keycloak/blob/1.7.x/integration/spring-securi... doesn't declare the default constructor.What am i missing?
