The JIRA issue for this work is FCREPO-648

Non-requirements

This work will NOT attempt to:

...

• 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
