• 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 and address circular module dependencies . Refactor to avoid circular dependency, else prepare to use setter injection.
  • DefaultAccess <--> DynamicAccessModule
  • DefaultDOManager <-->  FieldSearchSQLModule
  • DefaultDOManager <--> ManagementModule
  • ManagementModule <--> DefaultExternalContentManager
  • BasicServer <--> DefaultDOManager
  • DatastreamManagedContent <--> DefaultManagement
  • DisseminationService <--> DefaultAccess
  • Server <--> DefaultAuthorization
  (noted with on above page).
• Modify all classes to accept module dependencies and fcfg-configured values at construction time.
  • Decouple module interface impl from Module abstract class where needed
  • For those with circular dependencies that can't be refactored out, provide setters.
  Decouple module impls from Module abstract class (as is already done with ResourceIndexImpl/Module and others)

Phase II - Swap

• Decide on DI framework
• Convert fcfg to DI configuration
• Trigger initialization of module singletons via DI framework in context initialization
• Use injected dependencies only, avoiding use of Module and Server at runtime
