Notes on individual issues:
===========================
core-libs/java.util.jar:
JDK-8335912/JDK-8337499: Add an operation mode to the jar command when extracting to not overwriting existing files
===================================================================================================================
In previous OpenJDK releases, when the jar tool extracted files from
an archive, it would overwrite any existing files with the same name
in the target directory. With this release, a new option ('-k' or
'--keep-old-files') may be specified so that existing files are not
overwritten.
The option may be specified in short or long option form, as in the
following examples:
* jar xkf foo.jar
* jar --extract --keep-old-files --file foo.jar
By default, the old behaviour remains in place and files will be
overwritten.
core-libs/java.time:
JDK-8339637: (tz) Update Timezone Data to 2024b
===============================================
This OpenJDK release upgrades the in-tree copy of the IANA timezone
database to 2024b. This timezone update is primarily concerned with
improving historical data for Mexico, Monogolia and Portugal. It also
makes Asia/Choibalsan an alias for Asia/Ulaanbaatar and makes the MET
timezone the same as CET.
The 2024b update also makes a number of legacy timezone IDs equal to
geographical names rather than fixed offsets, as follows:
* EST => America/Panama instead of -5:00
* MST => America/Phoenix instead of -7:00
* HST => Pacific/Honolulu instead of -10:00
For long term support releases of OpenJDK, this change is overridden
locally to retain the existing fixed offset mapping.
New in release OpenJDK 21.0.5 (2024-10-15):
