- Change CommandDescription to contain a reference to ExecutableCommand class only
- Instantiate the actual ExecutableCommand objects in CommandHandler
- Separate FieldInjection from default fallback for no-Inject public no-args constructor classes
- Make CommandInitializer a normal, instantiable service
- Add various injections instead of fetching through command service
- Remove redundant uses of WrapperMock
- Use assertThat() from JUnit, not hamcrest
- Use hamcrest Matchers everywhere (not BaseMatchers etc.)
- Favor Mockito's argThat() over using ArgumentCaptor (more succinct)
- Delete useless test classes
- Move permissions responsibilities from command to permissions (remove some logic from CommandPermissions, add DefaultPermission enum to permissions package)
- Start possible interface for the future per-permission system implementations of permissions managers
- Change wrong player permissions to admin permissions
- Rename command class names that were the same for the ordinary vs. admin task
- Create test to ensure that commands with OP_ONLY default require an admin permission node
