- Remove SingleFilePersistenceHandler: DistributedFilesPersistenceHandler with segment size 1 can be used instead
- Rename SegmentFilesPersistenceHolder to DistributedFilesPersistenceHandler
- Rename SeparateFilePersistenceHandler to IndividualFilesPersistenceHandler to match LimboPersistenceType entry
- Add link to limbo page on Wiki in the settings
- Checkstyle config: allow todo comments with issue number
- Create consistency tests across all classes, ensuring: unique class names, users of expiring collectors implement HasCleanup, non-private fields are only constants
- Fix tag replacement in PlayerListener for {DISPLAYNAME}
- Introduce Usage.DEPRECATED to mark the hash algorithms accordingly
- Log warning when such a deprecated hash algorithm is used
- Update hash algorithms doc page
- Add usage message on argument mismatch where available
- Remove unused message keys
- Create tool task to search for a message key's usages and to find unused keys
- Add new checkstyle checks: require Javadoc on large private methods, default in switch, declaration order & others
- Update path exclusions in CodeClimate config to match newly renamed classes (e.g. PHPBB -> PhpBB)
- Create consistency check testing that excluded paths exist as classes
- Fix some trivial violations
- Update docs to reflect new commands, configurations (account recovery, limbo handling) and messages
- Change message for the recovery code email to contain the new command
- Create debug command to check if a player has the given permission
- Create debug command that outputs the size of various caches / DB info / number of saved instances in injector
* #1037 Improve architecture of registration methods
- Introduce parameters classes for each registration method
- RegistrationMethod has constants with the required parameters class -> no longer need to have a RegistrationExecutorProvider class that needs to be injected everywhere, let AsyncRegister be the only one to worry about which class will perform the registration
- Fix inheritance of password registration types - previously two-factor auth registration inherited from password registration directly
* Create matcher which checks for equality via reflections
- Allow to perform equality check on objects with default equals() method
