Chapter 2. Eclipse Temurin features Eclipse Temurin does not contain structural changes from the upstream distribution of OpenJDK. For the list of changes and security fixes that the latest OpenJDK 17 release of Eclipse Temurin includes, see OpenJDK 17.0.10 Released . New features and enhancements Review the following release notes to understand new features and feature enhancements included with the Eclipse Temurin 17.0.10 release: KEEPALIVE extended socket options support added on Windows On Windows 10 version 1709 or later platforms, the java.net.ExtendedSocketOptions class now supports the TCP_KEEPIDLE and TCP_KEEPINTERVAL options. Similarly, on Windows 10 version 1703 or later platforms, the java.net.ExtendedSocketOptions class now supports the TCP_KEEPCOUNT option. See JDK-8308593 (JDK Bug System) . X509KeyManager.chooseClientAlias method called once for all key types In OpenJDK 17.0.10, TLS or Datagram TLS (DTLS) now makes only one call to the X509KeyManager.chooseClientAlias method during handshakes for client authentication, regardless of how many algorithms are requested. See JDK-8262186 (JDK Bug System) . Peak values for committed memory included in NMT reports In OpenJDK 17.0.10, Native Memory Tracking (NMT) reports now show the peak value for all categories. The peak value is the highest value for committed memory in a given NMT category over the lifetime of the JVM process. If the committed memory for a category is currently at its highest value, the NMT report shows an at peak value; otherwise, the NMT report shows the historic peak value. For example, the following report output shows that compiler arena memory peaked above 6 MB but is now approximately 200KB: See JDK-8317772 (JDK Bug System) . JVM warnings about unsupported THPs on Linux On Linux platforms, if Transparent Huge Pages (THPs) are requested but not supported, the JVM now prints the following message to standard output: See JDK-8313782 (JDK Bug System) . Increased default value of jdk.jar.maxSignatureFileSize system property OpenJDK 17.0.8 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. OpenJDK 17.0.10 increases the default value of the jdk.jar.maxSignatureFileSize property to 16000000 bytes (16 MB). See JDK-8312489 (JDK Bug System) Let's Encrypt ISRG Root X2 CA certificate added In OpenJDK 17.0.10, the cacerts truststore includes the Internet Security Research Group (ISRG) Root X2 certificate authority (CA) certificate from Let's Encrypt: Name: Let's Encrypt Alias name: letsencryptisrgx2 Distinguished name: CN=ISRG Root X2, O=Internet Security Research Group, C=US See JDK-8317374 (JDK Bug System) .
