I have tried integrating tzdata2018i into jdk13 and found below tests are failing post integration.

java/time/test/java/time/format/TestZoneTextPrinterParser.java
java/time/tck/java/time/format/TCKDateTimeFormatterBuilder.java
java/text/Format/DateFormat/SDFTCKZoneNamesTest.java
java/text/Format/DateFormat/Bug8081794.java
java/text/Format/DateFormat/Bug4322313.java
sun/util/resources/cldr/Bug8202764.java
java/util/TimeZone/CLDRDisplayNamesTest.java

With the same patch jdk-12u and 11u all the tests are passing.

Below are the failures details:
1. java/time/test/java/time/format/TestZoneTextPrinterParser.java:
