Simplify CoarseSessionAttributes mutation tracking -------------------------------------------------- Key: WFLY-12820 URL: https://issues.jboss.org/browse/WFLY-12820 Project: WildFly Issue Type: Bug Components: Clustering Affects Versions: 18.0.1.Final Reporter: Paul Ferraro Assignee: Paul Ferraro Priority: Major CoarseSessionAttributes currently uses a ConcurrentHashMap<String, Boolean> for fine-grained tracking of the dirty state of the session. Now that we only mutate the session on close(), this can be simplified with a simple dirty flag.
