I would expect a test case with `jdk.calendar.japanese.supplemental.era` defined with something, and 7 would throw an IAE. src/java.base/share/classes/java/util/JapaneseImperialCalendar.java line 1862: > 1860: // BEFORE_MEIJI to be ignored during normalization > 1861: // We check against eras.length over Reiwa ERA due to > possibility > 1862: // of additional eras via > "jdk.calendar.japanese.supplemental.era" The possibility is not only that emergency property, but by design Japanese calendar eras increase when the current emperor abdicates. ------------- PR Review: https://git.openjdk.org/jdk/pull/23789#pullrequestreview-2645256501 PR Review Comment: https://git.openjdk.org/jdk/pull/23789#discussion_r1972020190
