[tz] need testing for new tzdb release for Brazil changes

Any planning already on this new release for the Brazil changes?
Our customers are getting worried as they are starting to run in date/times after the Brazil changes.

And after an official version is released we also have to run tests with the released version, that will also take time.

So would be good to have the new release available, or at least a set date on when we can expect it so we can plan time for internal testing before releasing the combination to our customers.

We plan to get a new release out reasonably soon, and well before November. 
However, there is no fixed schedule or specific plan. In the meantime I suggest that you test your software by using the tzdb development version and reporting your results back. You can currently retrieve it by running this command:

git clone https://github.com/eggert/tz

I would like more testing by people other than myself. It's quite possible that the next release will have problems and I want to hear bug reports and "it's all OK!" reports back. I'm not hearing anything, which leads me to suspect that a new release must not be that urgent.

Here is one longstanding issue that I would like to see progress on:


That is, Oracle TZUpdater fails to handle the forms of DST currently used in Ireland and Morocco, and historically used in Czechoslovakia, Japan and Namibia. 
Although this was reported as a P3 (major loss of function) bug in January 2018 <https://bugs.openjdk.java.net/browse/JDK-8195595>, I am not plugged into the JDK development effort and don't know what sort of progress is being made here.

Ramanand, you're assigned that bug report. What's the status of the fix for this issue, and of testing the fix? Have you tested with data taken from the current tzdb development version? Although I doubt whether the Brazil changes themselves will cause problems with TZUpdater I've been surprised in the past, and also the next release will contain changes not related to Brazil, so I'd appreciate some feedback here.
