Yes.

Once I am done with the chained transformers, I will look at pulling the legacy test controllers for both core-model-test and subsystem-test out into their own repository. That way they can be kept around without polluting the codebase. This should end the days of having 3 versions of WildFly/AS7 classes appear in the IDE classpath, which is annoying when you want to look up a class by name.

The point of allowing the 7.1.x testing again is to get better coverage while converting the chained transformer stuff so that I can work through problems while I remember how this works, rather than in many month’s time.

Currently I am trying to convert the jmx subsystem, and think I will also do the other ones in wildfly-core (remoting and logging).

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.
