PersistentComponent with Java Records deserializing issue

[Ali_RS]

It does mean that an application that uses records would have to add a factory for every component that is a record. I don’t see a way around that, though.

What is the issue with a general-purpose RecordComponentFactory that uses canonical constructor to initialize components?

Class<?> recordClass = ...;

RecordComponent[] components = recordClass.getRecordComponents();
Class<?>[] parameterTypes = new Class<?>[components.length];
for (int i = 0; i < components.length; i++) {
    parameterTypes[i] = components[i].getType();
}

Constructor<?> constructor = recordClass.getDeclaredConstructor(parameterTypes);
constructor.newInstance(args)
