Why doesn't Java autoboxing extend to method invocations of methods of the autoboxed types?

I want to convert a primitive to a string, and I tried: myInt.toString(); This fails with the error: int cannot be dereferenced Now, I get that primitives are not reference types (ie, not an Object) and so cannot have methods. However, Java 5 introduced autoboxing and unboxing (a la C#... which I never liked in C#, but that's beside the point). So with autoboxing, I would expect the above to convert myInt to an Integer and then call toString() on that. Furthermore, I believe C# allows such a call, unless I remember incorrectly. Is this just an unfortunate shortcoming of Java's autoboxing/unboxing specification, or is there a good reason for this?
