Re: [cdi-dev] Types of Principal object

Hi, We discussed this very issue in the Security API EG as well. In the Security API the actual type *MUST* be retained as per the spec definition. The problem in CDI, at least in Weld, is that a proxy is injected. This happens via the build-in bean "PrincipalBean extends AbstractEEBean", where AbstractEEBean does: public abstract class AbstractEEBean<T> extends AbstractStaticallyDecorableBuiltInBean<T> { private final T proxy; protected AbstractEEBean(Class<T> type, Callable<T> callable, BeanManagerImpl beanManager) { super(beanManager, type); this.proxy = new ProxyFactory<T>(beanManager.getContextId(), type, getTypes(), this).create(new EnterpriseTargetBeanInstance(type, new CallableMethodHandler(callable))); } // ... } I'm not even sure if it's possible to downcast the proxy to the required runtime type. Also note that the Principal can change during the request. The simplest case is when during an http request HttpServletRequest#logout is called.
