RELEASE NOTES FOR: 19.0.1 ==================================================================================================== Notes generated: Tue Dec 03 14:36:11 CET 2024 Hint: Prefix bug IDs with https://bugs.openjdk.org/browse/ to reach the relevant JIRA entry. JAVA ENHANCEMENT PROPOSALS (JEP): None. RELEASE NOTES: hotspot/gc: JDK-8292654: G1 Remembered set memory footprint regression after JDK-8286115 JDK-8286115 changed ergonomic sizing of a component of the remembered sets in G1. This change causes increased native memory usage of the Hotspot VM for applications that create large remembered sets with the G1 collector. In an internal benchmark total GC component native memory usage rose by almost 10% (from 1.2GB to 1.3GB). This issue can be worked around by passing double the value of `G1RemSetArrayOfCardsEntries` as printed by running the application with `-XX:+PrintFlagsFinal -XX:+UnlockExperimentalVMOptions` to your application. E.g. pass `-XX:+UnlockExperimentalVMOptions -XX:G1RemSetArrayOfCardsEntries=128` if a previous run showed a value of `64` for `G1RemSetArrayOfCardsEntries` in the output of `-XX:+PrintFlagsFinal`. This issue has been addressed in JDK 19.0.1 or later. core-libs/java.time: JDK-8292579: Update Timezone Data to 2022c This version includes changes from 2022b that merged multiple regions that have the same timestamp data post-1970 into a single time zone database. All time zone IDs remain the same but the merged time zones will point to a shared zone database. As a result, pre-1970 data may not be compatible with earlier JDK versions. The affected zones are ```Antarctica/Vostok, Asia/Brunei, Asia/Kuala_Lumpur, Atlantic/Reykjavik, Europe/Amsterdam, Europe/Copenhagen, Europe/Luxembourg, Europe/Monaco, Europe/Oslo, Europe/Stockholm, Indian/Christmas, Indian/Cocos, Indian/Kerguelen, Indian/Mahe, Indian/Reunion, Pacific/Chuuk, Pacific/Funafuti, Pacific/Majuro, Pacific/Pohnpei, Pacific/Wake, Pacific/Wallis, Arctic/Longyearbyen, Atlantic/Jan_Mayen, Iceland, Pacific/Ponape, Pacific/Truk, and Pacific/Yap```.
