ADDITIONAL SYSTEM INFORMATION :
Linux, open jdk8u242

A DESCRIPTION OF THE PROBLEM :
We are already using jdk version (8u242) that respects the latest timezone schedule for Brazil.

We are seeing a very weird issue happened only on DST transition date in Brazil, and only on the time when this transition happened

E.g.
1. for ZonedDateTime - 2018/11/03/00:00:00 in timezone "America/Sao_Paulo", if plus one day, it will return us 2018/11/04/01:00:00, you can see the hour is changed, this is not ideal
2. but if I set an hour, like 2018/11/03/01:00:00, after plus 1 day, it will return 2018/11/04/01:00:00 as expected
3. I tried the same thing with US timezone, it works as expected no matter the start time is right on the transition time (2 am) or other time, I also tried past years besides 2020, they all works as expected (i.e. plus one day without changing the hour)

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
for 2018-11-04 it should printout 2018-11-04T00:00-02:00[America/Sao_Paulo]
for 2017-10-15 it should printout 2017-10-15T00:00-02:00[America/Sao_Paulo]
ACTUAL -
2018-11-03T00:00-03:00[America/Sao_Paulo]
2018-11-04T01:00-02:00[America/Sao_Paulo]

---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
We have to truncate the date so it will return midnight time for us instead of 1am in Brazil
