I’ve got the chained transformers mostly working in its own tests, but have some issues to iron out when using them for real, which is not picked up by the tests I wrote. Currently I am trying to convert the jmx subsystem, and think I will also do the other ones in wildfly-core (remoting and logging). Since we have disabled transformer testing against WildFly 8, and AS 7.1.x, there isn’t actually much of a chain to test at the moment. To get better coverage of what I have done in real subsystem scenarios, I would like to temporarily reinstate the test controller for 7.1.x, and to use a system property to enable running of tests against 7.1.x and WildFly 8 unless someone has some strong objections. If people start converting to use chained transformers, since the 7.1.x tests already exist, I think this will be valuable validation of what they are doing.
