Hi Guys,

Please review the patch for tzdata2020b integration into JDK.

Release details can be found here:

https://mm.icann.org/pipermail/tz-announce/2020-October/000059.html

Bug: https://bugs.openjdk.java.net/browse/JDK-8254177

I had the pacificnew, systemv files removed from JDK repo and so TimeZoneName classes, make file and few test files need to be updated to incorporate the change.

The patch has passed all the related testing including JCK.

Thanks,
Kiran

Looks good to me.
I was wondering about the consequence of removing the "US/Pacific-New" zone names, but since the time zone should never have been introduced in the first place (it didn't become the law), I think no real world application would have used it.

Looks good. I think we should release-note the removal of the "US/Pacific-New" Link on the off chance that some production/testing system is looking for such a zone.

Looks like we both reached the same patch for this one independently :)
systemv was removed from tzdata some time ago and wasn't even being read by the JDK as far as I could see. Its contents are duplicated in jdk11_backward anyway.
Good to see both it and pacificnew being removed. In the unlikely event the removal of Pacific_New is problematic, it could be added to jdk11_backward as well, but it seems very unlikely.

Thanks for the comment, Andrew. I agree
