If you have used MountMapper for your custom mappers in Wicket 1.5/6.x then now your custom mapper has to extend from AbstractBookmarkableMapper.
Note: MountMapper and its related classes are still available in 7.x but deprecated and not used by Wicket itself. They will be completely removed in Wicket 8.0.0
