+For RestEasy, you need to include `resteasy-cdi` support to your project to ensure that dependencies are injected at runtime. Refer to the tests in `resteasy-pac4j` module.
 
 Note that a default value for the `clients` parameter of the `@Pac4JSecurity`
 annotation can be passed to the constructor of `Pac4JSecurityFeature`.
