I never know how people find this stuff, but, fair enough - you're entirely correct.

If it's interesting, I found it like this:

1. I had @Singular List<Foo> foos and wrote toBuilder().foos(extraFoos).build()
2. a colleague commented that I probably overwrite foos instead of appending
3. I explained to him this "quirk" of @Singular and directed him to a delomboked example
