> Currently, WildFly's distributed web session manager detects classes annotated with @Immutable placed into the web session, optimizes calls so HttpSession.getAttribute(...) are not treated as cache writes.
> However, users don't always have access to the classes to be able to annotate them, e.g. they come from a web framework, etc.
> The proposal is to add a public SPI that users can implement that provides a web application with a set of classes that should be treated as immutable with respect to the distributed web session manager.
