Deprecate default-stack JGroups subsystem attribute --------------------------------------------------- Key: WFLY-4194 URL: https://issues.jboss.org/browse/WFLY-4194 Project: WildFly Issue Type: Enhancement Components: Clustering Affects Versions: 9.0.0.Alpha1 Reporter: Paul Ferraro Assignee: Paul Ferraro Fix For: 9.0.0.Beta1 The original purpose of the default-stack attribute was to provide a default ChannelFactory implementation. However, with the introduction of fork channels, there are now 2 candidate for a default ChannelFactory: 1. The JChannelFactory of the default stack. 2. The ForkChannelFactory of the default channel. #2 is the better option - and is what Infinispan transports use by default. This would require that the stack attribute of a channel is required (currently, it is optional and defaults to the default-stack).
