Re: [Discussion] Upgrading JDK to 11 and removing support for Scala 2.11
Hi all,
Sorry for taking so long back here. We can continue the discussion on this
topic. Personally, I support upgrading to JDK 11. Welcome to hear more
opinions.
Best,
Huajie Wang

What do you think?

I also support the proposal to upgrade to JDK 11, the feasibility of which was discussed in an earlier thread [1], but note that we may be stuck with JDK 11 for a longer period of time in the future, as Flink's support for JDK 17 [2] is still a work in progress.

I support upgrading to JDK 11, and it will be better to set JDK11 as the
default compiled maven version (to guide users to upgrade), and also
prepare for JDK17 in the future
