I'm in the process of converting code for James 2.X to 3.8. I'm having some trouble storing an instance of an arbitrary class as a Mail attribute.
James 2.X supported storing Serializable objects directly as an Mail attribute. In James 3.X this was changed to a specialized procedure using JSON serialization. It looks like I need to implement ArbitrarySerializable to support storing arbitrary objects. There is example implementation of ArbitrarySerializable but that's only a simple example supporting an Integer which works because AttributeValue.of already supports Integer's. Can someone help me with an example on how to store complex objects as a Mail attribute? Kind regards, Martijn Brinkers
