Chapter 3. Red Hat build of OpenJDK features The latest Red Hat build of OpenJDK 11 release might include new features.

Note For all the other changes and security fixes, see OpenJDK 11.0.22 Released . Red Hat build of OpenJDK new features and enhancements Review the following release notes to understand new features and feature enhancements that Red Hat build of OpenJDK 11.0.22 provides: New JFR event jdk.SecurityProviderService Calls to the java.security.Provider.getService(String type, String algorithm) method now trigger a new JFR event, jdk.SecurityProviderService . The jdk.SecurityProviderService event contains the following three fields: Type: The type of service Algorithm: The algorithm name Provider: The security provider The jdk.SecurityProviderService event is disabled by default. You can enable this event by using the standard JFR configuration files and options. See JDK-8254711 (JDK Bug System) . Increased default value of jdk.jar.maxSignatureFileSize system property Red Hat build of OpenJDK 11.0.20 introduced a jdk.jar.maxSignatureFileSize system property for configuring the maximum number of bytes that are allowed for the signature-related files in a Java archive (JAR) file ( JDK-8300596 ). By default, the jdk.jar.maxSignatureFileSize property was set to 8000000 bytes (8 MB), which was too small for some JAR files, such as the Mend (formerly WhiteSource) Unified Agent JAR file. Red Hat build of OpenJDK 11.0.22 increases the default value of the jdk.jar.maxSignatureFileSize property to 16000000 bytes (16 MB).
