Deprecated configuration for TCPGOSSIP not usable ------------------------------------------------- Key: WFLY-11902 URL: https://issues.jboss.org/browse/WFLY-11902 Project: WildFly Issue Type: Bug Components: Clustering Affects Versions: 17.0.0.Beta1 Reporter: Richard Janík Assignee: Paul Ferraro Priority: Critical Related to WFLY-11901.

While this incompatibility is fine for WFLY, it is an issue for the product, where 17.0 will only translate to a minor version update.
