Thank you for that information. I researched this and was told that we support Java 8+, not just 8 and 11. We submitted a request to correct the documentation.

You should be able to use Java 17 now for your projects. Are you specifically asking for when we will support Java 17 (and perhaps later versions) when using External Java Server/Java Gateway? If that is the case then I believe you can do that in 2024.1.0.

I can provide a solution for this but it comes with warnings - SQL doesn't do well with polymorphic embedded objects. If that isn't an issue then consider using a factory pattern. You must define a base class that extends %SerialObject and it must be instantiable. Then, override %OnNew() to dispatch to the concrete class that you wish to instantiate. Perhaps pass in a type argument. That %OnNew() can return an OREF (or a %Status if an error occurs).

If you are interested in this model then I can provide a small demo.
