[jboss-jira] [JBoss JIRA] (WFCORE-4185) ReadMasterDomainModelUtil is including runtime-only attributes in what it provides

Brian Stansberry resolved WFCORE-4185.
--------------------------------------
    Resolution: Rejected


This is invalid.  When ReadMasterDomainModelUtil is doing this work, it is processing a *transformed* resource tree.  It cannot reason correctly about the contents of such a tree solely using the data in the ManagementResourceRegistration.

The JGroups subsystem, for example, places a 'type' attribute in the transformed resource model, for use by legacy HCs that expected it. That attribute is not present in the current MRR as it is not needed.

Conceivably we could only strip registered attributes that are runtime-only, but even then it is conceivable that a legacy version of the subsystem needed the value.

> Some resources (e.g. WildFly's transaction subsystem's log-store resource) may use the Resource tree DMR model node to store non-persistent, runtime-only state.  If this is done, any such value should not be propagated to a remote HC.
> (This is actually very unlikely to happen in practice as runtime-only attributes are not typically used in the domain model. It does affect transformer testing though as transformer tests usually don't take care to inform their extension that they are running in an HC.)
> Cleaning this up helps resolve WFCORE-4183 by removing irrelevant data that confuses domain mode transformer tests.
