POST https://graph.microsoft.com/beta/teams/57fb72d0-d811-46f4-8947-305e6072eaa5/channels/19:[email protected]/messages
Content-type: application/json

{
   "createdDateTime":"2019-02-04T19:58:15.511Z",

Erroneous 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",
                     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.
