             Summary: Subsystem parsers should be created lazly when need
                 Key: WFCORE-1841
                 URL: https://issues.jboss.org/browse/WFCORE-1841
             Project: WildFly Core
          Issue Type: Enhancement
          Components: Domain Management
            Reporter: Tomaz Cerar
            Assignee: Tomaz Cerar


Currently when we register parsers for different versions of subsystem schema we always pass over instance of whole parser which is usually statically initialized.
In practice legacy (non current) parsers are only used rarely and there is no point in having them loaded in memory when not needed.

Impl should be based on provider pattern and as such also allow us to on demand create new instance of parser when needed, as well as enable us for parsers to be GCed, when they are not in use.
