Packaging a Project With Nativize Blueprints Enabled Fails With Setter for an Array of Classes

Packaging failure occurs with nativize blueprints enabled when you have an array of classes and you try to set it with an array from an instance of a native C++ class.

Found in 4.15.1. Reproduced in 4.14.3 and 4.16 Main CL# 3354254

1. Open the editor
2. Add a new C++ class based on Actor
3. In <ProjectName>GameModeBase.h, add the following code:

   public:		
   
   	UPROPERTY(BlueprintReadOnly, Category = "Test")
   	TArray<TSubclassOf<AMyActor>> ActorClasses;
   

4. Compile
5. Back in the editor, create a new blueprint actor class and add an array of MyActor classes (ensure that they are not references, but classes)
6. On BeginPlay, Get Game Mode and cast it to <ProjectName>GameModeBase
7. Pull off the return value of the cast node and get ActorClasses
8. Pull off of the getter and add a Set node for your array of MyActor classes
9. Compile & Save
10. Navigate to Project Settings->Packaging and set Blueprint Nativization Method to Inclusive
11. Package for Win64

Result: Packaging fails with the following error:

Expected: No error would occur
