What’s New$$$This release contains the following updates and new features.$$$$$$Notable Changes$$$This is the list of the notable issues fixed in this release.$$$$$$Issue IDt$$$JDK-8212084$$$$$$Summary: G1: Support UseGCOverheadLimit$$$$$$Description: The G1 garbage collector now throws an OutOfMemoryException (OOME) when the garbage collection overhead is more than GCTimeLimit percent (default value 98) and the free Java heap is less than GCHeapFreeLimit percent (default value 2) for five consecutive garbage collections. This feature is enabled by default. It can be disabled using the -XX:-UseGCOverheadLimit option. The implementation mirrors the functionality already provided by the Parallel garbage collector. However there may be differences in the exact conditions for the OOME triggers as G1 calculates garbage collection overhead and free Java heap slightly differently.$$$$$$JDK-8372351$$$$$$Summary: Added WISeKey Global GB and GC Root CA Certificates$$$$$$Description: wisekeyglobalrootgbca and wisekeyglobalrootgcca root certificates have been added to the cacerts truststore.$$$$$$Builds of Liberica JDK With CRaC$$$This release of Liberica JDK includes full CRaC support. CRaC support is available for Liberica JDK 17 and 21. For more information; see Using CRaC with Java applications.$$$$$$IANA TZ Data version$$$This release of Liberica JDK 21.0.12 comes with the 2026b version of the in-tree copy of the IANA timezone database. The following are the key features of this version.$$$$$$Briefly$$$British Columbia moved to permanent -07 on 2026-03-09.$$$$$$Some more overflow bugs have been fixed in zic.$$$$$$Changes to future timestamps$$$British Columbia’s 2026-03-08 spring forward was its last foreseeable clock change; as it moved to permanent -07 thereafter. (Thanks to Arthur David Olson.) Although the change to permanent -07 legally took place on 2026-03-09; temporarily model the change to occur on 2026-11-01 at 02:00 instead. This works around a limitation in CLDR v48.2 (2026-03-17). This temporary hack is planned to be removed after CLDR is fixed.$$$$$$Changes to code$$$zic no longer mishandles a last transition to a new time type.$$$$$$zic no longer overflows a buffer when generating a TZ string like PST-167:59:58PDT-167:59:59;M11.5.6/-167:59:59;M12.5.6/-167:59:59; which can occur with adversarial input. (Thanks to Naveed Khan.)$$$$$$zic no longer generates a longer TZif file than necessary when an earlier time zone abbreviation is a suffix of a later one. As a nice side effect; zic no longer overflows a buffer when given a long series of abbreviations; each a suffix of the next. (Buffer overflow reported by Arthur Chan.)$$$$$$zic no longer overflows an int when processing input like ‘Zone Ouch 2147483648:00:00 - LMT’. The int overflow can lead to buffer overflow in adversarial cases. (Thanks to Naveed Khan.)$$$$$$zic now checks for signals more often.$$$$$$For more information; see JDK-8383175.$$$$$$3.
