For the record:
Netty 4.1.67 moved the TCP_FASTOPEN config from io.netty.channel.epoll.EpollChannelOption to io.netty.channel.ChannelOption (netty pr: netty/netty#11559), which influences the way it needs to be set in Play's application.conf. So this made scripted tests fail in this pr (which is targeted against the 2.8.x branch)
Interestingly enough however our master branch is using netty 4.1.67+ since almost four month now, but the scripted tests there never complained... That's because on master we don't even run scripted tests anymore for PR builds 😢 By default only scripted tests for sbt 1.3 ran, but in #10956 we removed support for sbt 1.3, including the associated scripted tests. So what was left were the scripted test for sbt 1.5 which are configured to run only for cron builds however. But, as we know, the cron build for the master branch is broken, so even the sbt 1.5 scripted tests never ran on master...
Anyway, I added the needed netty fixes for the master branch as part of #10969 and also enabled the sbt 1.5 scripted tests for PR builds there as well.
