[wildfly-dev] Management Parser Versioning

Working with the parsers for the core config has become increasingly cryptic, we are now at the point where we have three different major versions which diverge and converge as we work on them. Most recent changes have resulted in large sections of the config converging for 1.x and 3.x leaving 2.x independent. So that I can add references to Elytron I am starting to add support for version 4. One think that I have learned is that each major version tends to belong to one branch of the codebase, all changes to that version happen on that branch first: - 1.x - Maintained only for EAP 2.x - WildFly 8.x branch 3.x - WildFly Core master branch I would expect if further changes are made to core for WildFly 9 releases we will end up with 1.x branch of core and and 4.x version of the schema will be owned by the master branch. To make things less cryptic I am proposing that until we find a better solution for all subsequent major schema versions we just fork the parser and all related classes. This will simplify the code being modified for the upstream development. Forward porting parsing changes will also become a simple copy and paste. For the current cryptic approach I think almost every engineer (and I am finding it really hard to think of exceptions) that has worked in-depth in this area has introduced at least one bug and I don't think the test coverage is high enough to protect against this.
