Re: [hibernate-dev] Continue to add 5.2 deprecations for 6.0 work?

> there are cases where we deprecate something > with no replacement whatsoever Ah, so you are using deprecation to give users a heads-up that some API will be removed in a future release, but there's no replacement available yet? In that case I'd indeed go for a separate annotation such as your @EndOfLife, as it's more an information point at this point in time rather than some actionable warning. @Deprecated in my understanding should only be used if there's an alternative available, as otherwise I see how it creates frustration - users get a warning about using a deprecated API without a way of addressing this warning. Or, ideally, you'd add the replacement API already right now (so any @Deprecated warnings can be acted on by users), but I reckon it's not doable due to complexity etc. 2017-06-28 19:32 GMT+02:00 Steve Ebersole <steve(a)hibernate.org&gt;: > On Wed, Jun 28, 2017 at 12:12 PM Sanne Grinovero <sanne(a)hibernate.org&gt; > wrote: > >> >> The @Deprecated annotation is also evolving; for example in Java 9 it >> will have some additional attributes: >> - http://download.java.net/java/jdk9/docs/api/java/lang/Deprecated.html > > > The only additional data point I had proposed on @EndOfLife is the removal > version[1].
