Erroneous output:

             From = new ChatMessageFromIdentitySet
             {
                 User = new Identity
                 {
                     Id = "id-value",
                     DisplayName = "Joh Doe",
                     UserIdentityType = TeamworkUserIdentityType.AadUser
                 }
             },
             Body = new ItemBody
             {
                 ContentType = BodyType.Html,
                 Content = "Hello World"
             }
         };
         await graphClient.Teams["{team-id}"].Channels["{channel-id}"].Messages
             .Request()
             .AddAsync(chatMessage);

Expected output:

        GraphServiceClient graphClient = new GraphServiceClient( authProvider );
         var chatMessage = new ChatMessage
         {
             CreatedDateTime = DateTimeOffset.Parse("2019-02-04T19:58:15.511Z"),
             From = new ChatMessageFromIdentitySet
             {
                 User = new Identity
         { 
            Id = "id-value",
                DisplayName = "Joh Doe",
            AdditionalData = new Dictionary<string, object>()
            {
                {"userIdentityType", "aadUser"}
            }
         }
             },
             Body = new ItemBody
             {
                 ContentType = BodyType.Html,
                 Content = "Hello World"
             }
         };
         await graphClient.Teams["{team-id}"].Channels["{channel-id}"].Messages
             .Request()
             .AddAsync(chatMessage);

Fixed for C# in SDK v5. Still an issue for Java.
