The JBossWS integration with Spring has been evolving a lot since the initial prototype in 3.x series. WIth the latest additions in JBossWS 5 (see linked jiras), it's now time to deprecate the Spring integration, that is the ability of declaring ws endpoints and clients using spring based descriptors. This has proven to be a difficult to maintain solution and with the current stack functionalities there's really no reason for relying on it. We do have valid alternatives for configuring interceptors, features, setting WS-* options, controlling CXF internals, performing injection into EE components, etc.
In any case, the Spring integration has been disabled by default (optionally turned on by manually installing spring module on the container) since JBoss AS 7 series and users should now be properly relying on plain JAX-WS whenever possible and using WS-Policy and JBossWS configuration properties for advanced WS-* functionalities, so this is not going to be that an issue to the majority of the user base.
