Distributable session manager cannot detect immutable external classes ---------------------------------------------------------------------- Key: WFLY-11854 URL: https://issues.jboss.org/browse/WFLY-11854 Project: WildFly Issue Type: Enhancement Components: Clustering Affects Versions: 16.0.0.Final Reporter: Paul Ferraro Assignee: Paul Ferraro Priority: Major 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.
