How to handle future backports from JDK 10 into JDK 9?

[Mikael Vidstedt]

Joe,

Please go ahead with the suggested change. Let’s keep our eyes open to see what kinds of problems we run into and course correct if needed!

Cheers,
Mikael

However, I don't think such rare cases should drive larger decisions of handling forward and backports in 9 and 10 and whether or not the duplicate bug id check should be disabled in JDK 10.

(Sharing of scripts to do such checks pre-push welcome.) Additionally, the duplicate bug id check causes complications, including the topic under discussion now, as well as for the possible repository consolidation. That check has been disabled in the update releases for years without problems.

Take an example of an issue that is fixed but is buggy and has quite a lengthy bugtail - once it is reliable you want to backport it to an earlier release. Do you backport each individual bug (some of which may not even apply to the earlier release) or do you backport the resulting functionality that was finally obtained? There are pros and cons to both approaches - neither is clean nor ideal. Such is life.
