More like 25. C# 1.0 already had capabilities Java developers are still dreaming of, like structs / value types, properties and operator overloading. C# 2.0 in 2005 introduced generics, implemented far more competently than Java ever did.
Notice you point out features that were easy to add during the beginning where there was no concern of backward compatibility? Now that java is porting value classes to mainline and we might have them soon, and planned operator overloading through type class, I believe java approach is making careful design choices that are semantically sound, rather than adding features that create edge cases such as boxing invariants in unions like C#.
So you try to say that Java gets to be more semantically sound by making bad choices early on? That does not make sense. Those choices are very difficult fix today and many of them can't be fixed. Say what you want but semantically more sound Java won't be. And the boxing with C# unions can and will be addressed later, this was a deliberate choice by the team to bring unions earlier.

The difference is BDFL or design by committee, a big difference between both ecosystems.
