    I have some JSF beans managed by Spring using @Configurable and compile time weaving. Then I have a session scoped bean: {code:xml} <bean id="currentUser" factory-bean="authenticationUserService" factory-method="loadCurrentUser" scope="session" lazy-init="true" /> {code} When Tomcat shuts down, it persists the active sessions. When it starts it tries to restore those sessions, which triggers this exception: {noformat} SEVERE: Exception loading sessions from persistent storage
