> The problem is with how java reflection handles arrays. Different JDKs and supposedly even different methods in the same JDK use two different representations of an array:

> Note that there's a little overlap between Class and GenericArrayType. a type like String[] can be represented either as String[].class or GenericArrayType(String.class). Different JDK methods return different forms (I filed a bug on this but forgot which one), so your code should anticipate both patterns.
> {quote}
> In JDK6 {{new TypeLiteral<Integer[]>() {}.getType()}} returns {{GenericArrayType(Integer.class)}}, while in JDK7 it returns {{Integer[].class}}. 
> Since {{Integer[]}} is not a generic array, we can skip using {{TypeLiteral}} and simply use {{Integer[].class}} as the expected value. However, {{TypeVariableResolver}} should also be modified so it never returns {{GenericArrayType}}, when the array isn't generic.
