Same here; you need to create a new constructor and mark the old one @Deprecated.

I'll note that this sort of redundancy could be avoided by using a value object as the constructor argument rather than all of its attributes, but this would require a larger effort to fix at this point.

You need to keep the old constructors and mark them @Deprecated in order to preserve backward compatibility as this class is public.

Also, you should use an argument type of either int (for a required value) or Integer (for a nullable one). I'd suggest OptionalInt as an argument type for the latter, though I'm not sure if that actually works with @DataBoundConstructor.
