Would these changes impact the WildFly transaction mode [5]? Is the WildFly "NON_XA" transaction mode mapping to the 1PC option? Or Does WildFly NON_XA map to something else in Infinispan?
I'm not sure how this would impact WFLY-2267 [6], which is about attempting to register a synchronization too late.
