[~brian.stansberry], [~jmesnil] these are the operations the console invokes when dealing with resource adapters:

* Read r-r-d metadata for the column and application view (invoked only once if the metadata was not cached yet): 
  {{/subsystem=resource-adapters/resource-adapter=*:read-resource-description(access-control=trim-descriptions,operations=true,recursive-depth=3)}}
* List all resource adapters in the finder column: 
  {{/subsystem=resource-adapters:read-children-resources(child-type=resource-adapter)}}
* View one resource adapter in the application view: 
  {{/subsystem=resource-adapters/resource-adapter=<name>:read-resource(include-aliases=true,recursive=true)}}

> We have about 25 resource adapters set through CLI. When I want to display them in web administration console it kills the whole wildfly server - server is not responding and after several minutes it ends up with OutOfMemory error and server must be restarted. We've seen this issue since wildfly 10 (it was the first version we used). With only a few resource adapters it is not happening.
