Current org.jboss.as.transaction module is heavy lifting and has many dependencies and lot of work competencies. E.g. org.jboss.jts module depends on that too.
It should be investigated how to disentangle all the dependencies.
Plus this could be beneficiary for WildFly Swarm if we are able to split the dependency chains, maybe not using one big jar in the transaction module but provide more granularity. Needs to be investigated.
See attached image for a view of dependencies.
