I wasn't expecting a complete replacement of the Date(), but more a way to either set the date or skip the date in the comment( like setCommentDate(Date date) ). As one might see in the code, writing properties is not that easy. My concern is that any third party attempt to do this on its own will not be as good as the original implementation. Being in a situation to trying to get reproducible builds to OpenJDK itself, I understand your pain and fully support the idea that it should be at least possible for the standard methods to produce reproducible output. Adding an additional property to ignore the date, or set it to a given fixed date, seems like a very good idea to me. ... So I'd strongly recommend adding a second property to enforce sorted (or "stable" by some other definition) output, to be fully certain to achieve reproducibility.
Rather than add configuration state to this already (over!) complicated
class, wouldn’t a simple storeCanonical method do the trick? It would
just write the entries in key-name order, without any comments.
