[wildfly-dev] ObjectType Review /subsystem=elytron/properties-realm=*

[Darran Lofthouse]

A number of resources have been flagged within the Elytron subsystem 
requesting that we review the use of ObjectTypes (and similar) within 
the resource definitions.

Some I know we can simplify but others I would like to get a second 
opinion on, firstly I wanted to look at the 'properties-realm' resource.

This is a realm implemented to make use of the legacy properties files 
users of AS7 through WF10 will be familiar with so we need to reference 
two different properties files with the group-properties being optional.

Where a file is referenced it is common to reference both a path and a 
relative-to, rather than looking to find unique names for two path 
attributes and unique names for two relative-to attributes I have 
wrapped in specific OBJECT type attributes.

I could achieve a similar grouping by flattening and using attribute 
groups but then the path and relative-to attributes would require unique 
names.  Personally I just felt that for two attributes always used as a 
pair it was cleaner to wrap them into one.

Note:  Checking the output myself the path should not be nillable and 
the relative-to should not allow expressions so those two will be corrected.
