[forge-dev] Create serialVersionUID field on mapped @Entity classes, yes / no?

[Pete Muir]

Maybe I said it. It's not good practice to put serialVersionUID=1L, as it's broken in reality (all versions are now the same version). If you omit it entirely, then the JVM will compute the serialVersionUID for you on the fly, from the class file. This is much better for development. Once your app has stabilised, you can then go through and generate the ids needed. Instead of adding the serialVersionUID, I would suggest adding the relevant @SuppressWarnings("serial") (IIRC, that is the one).
