Doubtful. I'd guess it's a general utility library like Guava, where they're doing something with heterogeneous type "vararg" methods. Often they'll have a number of overloads to give the most type help, before reverting to less helpful vararg types. Anything that's heterogeneous, with dynamic arity to the library but known static types to the caller would be a good candidate. Like NTuple type implementations.
