- List all dependents of existing module interfaces
Identify and remove unused modules and classes with module dependencies. - Remove ReportServlet - FCREPO-646
- Remove ThreadMonitor - FCREPO-647
- Identify circular module dependencies (noted with

Modify existing modules to accept

injected dependencies and config values
- Decouple module interface impl from Module abstract class where needed
- Push param validation responsibility down to each impl (not in Module)
