[hibernate-dev] ScrollableResults and 6.0

[Yoann Rodiere]

For what it's worth, changing the signature indeed seems appropriate to me:
the fewer object arrays, the better.
Your proposal would require making Query parameterized too, though. I'm not
really up-to-date with the current state of 6.0, but I guess it's already
done or being done.

Anyway, the only think I wanted to say was: if we break the API, maybe we
should try to make sure we won't have to break it again soon. There has
been some discussions about adding scrolling to the JPA spec:
https://java.net/jira/browse/JPA_SPEC-89 . Maybe it would be worth it to
ask for advice on this ticket, so as to limit the risk of having to break
this API again, because the spec would introduce an incompatible signature?
Not sure there would be many reactions, judging by the low activity on the
ticket, but who knows...
