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-8292177$$$$$$Summary: New JFR Event: jdk.InitialSecurityProperty$$$$$$Description: A new Java Flight Recorder (JFR) event has been added to record details of initial security properties when loaded via the java.security.Security class. The new event name is jdk.InitialSecurityProperty and contains the following fields: key - Security Property Key; value - Corresponding Security Property Value. This new JFR event is enabled by default. The java.security.debug=properties system property will also now print initial security properties to the standard error stream. With this new event and the already available jdk.SecurityPropertyModification event (when enabled since it is not enabled by default); a JFR recording can now monitor the initial settings of all security properties and any subsequent changes.$$$$$$JDK-8372351$$$$$$Summary: Added WISeKey Global GB and GC Root CA Certificates$$$$$$Description: wisekeyglobalrootgbca and wisekeyglobalrootgcca root certificates have been added to the cacerts truststore.$$$$$$JDK-8381551$$$$$$Summary: DisabledCurve test fails on Windows after disabling SHA1$$$$$$Description: sun\\security\\ssl\\CipherSuite\\DisabledCurve.java test failed on Windows with Server failed: javax.net.ssl.SSLException: No supported signature algorithm for EC key error. The test started to fall after disabling SHA1 algorithms in TLS handshake by JDK-8340321. Test passed if ecdsa_sha1 usage HandshakeSignature is removed from the java.security file. Without SunMSCAPI; the test server used the ecdsa_sha224 signature algorithm; but it was unavailable if the SunMSCAPI provider was enabled.$$$$$$Builds of Liberica JDK With CRaC$$$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 17.0.20 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 info
