Consider the Oxygene code:
namespace TestSequenceNet;
uses
RemObjects.Elements.RTL;
type
BaseClass = public class end;
DerivedClass = public class(BaseClass);
type
Program = class
public
class var fList: List<DerivedClass>;
class method GetSequence: sequence of BaseClass; virtual; iterator;
begin
yield fList; /java under Elements 2331: Type mismatch, expected BaseClass
end;
class method Main(args: array of String): Int32;
begin
fList := new List<DerivedClass>;
for each El in GetSequence do;
end;
end;
end.The problem:
Until Elements 2289, this code compiled and run well under both .NET and java.
With Elements 2331:
Under .NET: Everything remains fine, as before.
Under java: Does not compile, giving the error as indicated in the code.
So, what happened between 2289 and 2331? The error message is pretty clear, but this change breaks a lot of my code.
