For the WildFly use of ServiceContributor [1], which registers for each SF/EMF, the 2lc RegionFactoryInitiator + JtaPlatform, I am worried that we don't yet have a "per app deployment" way to disable the WF ServiceContributorImpl. I'm thinking that some applications (e.g. Spring) may not want to use the WF 2lc RegionFactoryInitiator + JtaPlatform classes. To accomadate that need, I'm thinking of introducing WF configuration properties for controlling this: * wildfly.jpa.jtaplatform will default to true but if set to false, [1] will not call serviceRegistryBuilder.addInitiator(new WildFlyCustomJtaPlatformInitiator()). * wildfly.jpa.regionfactory will default to true but if set to false, [1] will not call serviceRegistryBuilder.addInitiator(new WildFlyCustomRegionFactoryInitiator()). My request is that we keep the StandardServiceRegistryBuilder.getSettings() call and document that in the future, instead of removing it, we will change it to return a read only copy of the configuration settings. Then, I can update [1] to check for these new properties and know that I can depend on using StandardServiceRegistryBuilder.getSettings(). An alternative could be to add a new method StandardServiceRegistryBuilder.getReadOnlySettings(). I'd like to make the WF code change now for WF13, so a quick response is appreciated! :) Scott [1] https://github.com/scottmarlow/wildfly/blob/WFLY-10427/jpa/hibernate5_3/s... _______________________________________________ hibernate-dev mailing list hibernate-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/hibernate-dev
