![]() that disables TLS extensions used by TLS servers.Ī disabled TLS extension does not form part of a TLS handshake process.that disables TLS extensions used by TLS clients.These system properties are detailed as follows: You can use two new system properties to disable Transport Layer Security (TLS) extensions for the TLS protocol. System properties for disabling TLS extensions Before the OpenJDK 11.0.14 release, this behavior was not possible if you updated your Microsoft Windows operating system or Microsoft Windows Server to a later version. OpenJDK that runs on either Microsoft Windows 11 or Microsoft Windows Server 2022 now displays the correct Microsoft Windows version in the os.name value of the System.getProperty() system property and any HotSpot error logs. Compression level values range from 1 through 9, with the value of 1 as the fastest setting and the value of 9 as the slowest setting.įor more information about the gz integer option, see JDK-8250554. You can use this option to enable gzip compression and to set a compression level when creating a heap dump. OpenJDK 11.0.14 adds the gz integer option to the GC.heap_dump diagnostic command of the jcmd utility. New option for the GC.heap_dump diagnostic command OpenJDK now identifies the correct version on these systems. OpenJDK’s identification of Microsoft Windows versionsīefore the OpenJDK 11, the os.name system property that is retrieved from System.getProperty() and the HotSpot error logs would report Windows 10.0 on Microsoft Windows 11 and Windows Server 2019 on Microsoft Windows Server 2022. ![]() For more information about the 2021b release, see 2021b release of tz code and data available on the IANA website.įor more information about IANA’s Time Zone Database, see Time Zone Database on the IANA website.įor more information about IANA’s 2021c Time Zone Database release, see JDK-8274857. The 2021b release of the Time Zone Database updated time zone rules that existed before 1970. Red Hat OpenJDK on Microsoft Windows uses the latest available CA certificate from RHEL. Red Hat OpenJDK on Microsoft Windows includes the latest available timezone data from RHEL. Red Hat OpenJDK on RHEL uses system-wide CA certificates. Red Hat OpenJDK on RHEL uses system-wide timezone data files as a source for timezone information. The src.zip file includes the source for all the JAR libraries shipped with OpenJDK. RHEL also dynamically links against Harfbuzz and Freetype for font rendering and management. Red Hat OpenJDK on RHEL dynamically links against native libraries such as zlib for archive format support and libjpeg-turbo, libpng, and giflib for image support. ![]() This change does not apply to OpenJDK builds for Microsoft Windows. You can set different security profiles to balance safety and compatibility. These configuration components are used by the Transport Layer Security (TLS) encryption protocol, the certificate path validation, and any signed JARs. Red Hat OpenJDK 11 obtains the list of enabled cryptographic algorithms and key size constraints from RHEL. This change does not apply to OpenJDK builds for Microsoft Windows.Ĭryptographic policy support. ![]() Red Hat OpenJDK 11 automatically detects whether RHEL is in FIPS mode and automatically configures OpenJDK 11 to operate in that mode. ![]()
