Chapter 3. Red Hat build of OpenJDK 8.0.382 release notes The latest Red Hat build of OpenJDK 8 release might include new features. Additionally, the latest release might enhance, deprecate, or remove features that originated from Red Hat build of OpenJDK 8 releases. Note For all the other changes and security fixes, see OpenJDK 8u382 Released . Red Hat build of OpenJDK new features and enhancements Review the following release notes to understand new features and feature enhancements that the Red Hat build of OpenJDK 8.0.382 release provides: Support for GB18030-2022 The Chinese Electronics Standardization Institute (CESI) recently published GB18030-2022 as an update to the GB18030 standard, synchronizing the character set with Unicode 11.0. The GB18030-2022 standard is now the default GB18030 character set that Red Hat build of OpenJDK 8.0.382 uses. However, this updated character set contains incompatible changes compared with GB18030-2000, which releases of Red Hat build of OpenJDK 8 used. From Red Hat build of OpenJDK 8.0.382 onward, if you want to use the version of the character set, ensure that the new system property jdk.charset.GB18030 is set to 2000 . See JDK-8301119 (JDK Bug System) . Additional characters for GB18030-2022 (Level 2) support allowed To support "Implementation Level 2" of the GB18030-2022 standard, Red Hat build of OpenJDK must support the use of characters that are in the Chinese Japanese Korean (CJK) Unified Ideographs Extension E block of Unicode 8.0. Maintenance Release 5 of the Java SE 8 specification adds support for these characters, which Red Hat build of OpenJDK 8.0.382 implements through the addition of a new UnicodeBlock instance, Character.CJK_UNIFIED_IDEOGRAPHS_EXTENSION_E . See JDK-8305681 (JDK Bug System) . Enhanced validation of JAR signature You can now configure the maximum number of bytes that are allowed for the signature-related files in a Java archive (JAR) file by setting a new system property, jdk.jar.maxSignatureFileSize . By default, the jdk.jar.maxSignatureFileSize property is set to 8000000 bytes (8 MB). JDK bug system reference ID: JDK-8300596.
