What Operating System are you using (both controller, and any agents involved in the problem)?

Reproduction steps

1. Create configuration with Casc, reload

unclassified:
  lockableResourcesManager:
    declaredResources:
      - name: "foo"
      - name: "bar"
      - name: "waldo"

2. Check things looking fine
3. Create another configuration with Casc, reload:

unclassified:
  lockableResourcesManager:
    declaredResources:

Expected Results

I expect the declared resources are all removed

Actual Results

The declared resources are still there. I tried different things, like completely not loading in any "lockableResourcesManager", or like loading the below without delcaredResources:

unclassified:
  lockableResourcesManager:

it does not work

However, trimming down the list works:

unclassified:
  lockableResourcesManager:
     declaredResources:
      - name: "foo"
      - name: "bar"

This will successfully remove Waldo.

Anything else?

I think, this is how the JcAC works. Probably nothing todo with Lockable Resources.
