Hi, Gunnar!
Thank you for your feadbacks. 
Here I want mind and can change it, but somedays Oleg or Gary pointed me out that JavaDoc should be more formal and as less as possible.
IMO `see {@link #registerRequestMappingHandlerMappingIfNecessary}` is just enough.
I'm waiting more comments and fixing them, if needed. 
Let me know when there won't be more concerns
