In the public api where a method signature specifies a parameter of List<Option> that should be List<? extends Option> so that the user doesn't have to cast a List<QueryOption> to List<Option>.

For example, in com.microsoft.graph.requests.generated.IBaseMessageRequestBuilder:

IMessageRequest buildRequest(java.util.List<Option> requestOptions);

should be

IMessageRequest buildRequest(java.util.List<? extends Option> requestOptions);
