Cons
Con Can be very slow
Con Slightly over-engineered
Very enterprisey - made for huge architectures and with tons of declarative, non-intuitive annotations it makes it overkill for very small projects.
Con Native i18n support over-engineered
Not developer-friendly. Switching languages need reloading the whole page. There are third party solutions that work better.
