private static TypeDescriptor createTypeDescriptor(Method method, int paramIndex) {
	Parameter parameter = method.getParameters()[paramIndex];
	MethodParameter methodParameter = MethodParameter.forParameter(parameter);
	TypeDescriptor typeDescriptor = new TypeDescriptor(methodParameter);

	// Feign applies the Param.Expander to each element of an Iterable, so in those
	// cases we need to provide a TypeDescriptor of the element.
	if (typeDescriptor.isAssignableTo(ITERABLE_TYPE_DESCRIPTOR)) {
		TypeDescriptor elementTypeDescriptor = getElementTypeDescriptor(
				typeDescriptor);

		checkState(elementTypeDescriptor != null,
				"Could not resolve element type of Iterable type %s. Not declared?",
