This looks incorrect.

The formatting is being changed on the 2015 Fiji line in australasia and a line
is removed from the copy of the europe file in the test tree.

Corrected version:

https://cr.openjdk.java.net/~andrew/openjdk8/8254982/webrev.01/

Note that, although it doesn't affect this particular change, tzdata for 8u
needs to be converted to rearguard format, not simply backported.

I was planning to do tzdata2020c & tzdata2020d in one patch for this reason,
but I guess we can go with this one alone now.

Please review the revised webrev and then we can push.

Thanks,
