Thanks for the constructive advice and I agree that check and synchronizing 
between different branches are one important aspect we should pay more 
attention to. I will bring this discussion to the dev community to attract more 
committer’s and contributor’s attention later.

For this specific issue, since it’s a known UT bug, I tend to fix it in the 
next release and continue with this RC vote.

Saying about UT, I’d like to discuss a little bit more about it here: 
currently, we have some UTs (3-4 as I know) that are not stable enough 
themselves, which means they cannot verify features as expected or they may 
sometimes mis-warn us with failures limited to their own bad logic, and even 
worse over time, we may be less alert to UT failures. I would suggest we fix 
these unstable UTs as soon as possible, or at least, if they are not on the 
schedule now, we should list all these unstable UTs and the possible failures 
and reasons for failure to reduce the confusion of developers and verifiers.

The first release was relatively smooth. But in this release, with all the 
problems encountered, we have learned that there’re still some things lacking 
in the community to guarantee regular Apache releases with high quality and 
efficiency. The Dubbo community has worked on with the following aspects to 
improve that: 
* How to prepare an Apache release [1].
* The checklist for release candidate [1].
* Release script to automate the release process [2].

Best regards,
