Note that you must have an Oracle account to be able to download JDK 11 installer. Oracle JDK 11 comes with installers for Linux (rpm and deb), macOS (dmg), Windows (exe) and archive files (tar.gz and zip).For Windows, I recommend to download the file jdk-11.0.7_windows-圆4_bin.exe. According to Oracle, JDK 11 will be supported (commercial support) until September 2026.Head to Java SE Development Kit 11 Downloads page and choose the download file appropriate to your operating system.
Download and Install Oracle JDK 11Oracle JDK 11 is the first LTS (Long Term Support) Java Development Kit since Oracle changed Java release cadence to every 6 months. You know, Oracle released Java 11 builds under two different licenses: Oracle JDK (commercial build with Oracle Technology Network license) and OpenJDK (open source build with GNU General Public license). This has now been fixed.In this post, I will guide you to setup Java 11 on Windows operating system by downloading and installing Java Development Kit (JDK) version 11 from Oracle. Running jps as root does not show all informationĪfter the fix of JDK-8050807 (fixed in 8u31, 7u75 and 6u91), running jps as root did not show all the information from Java processes started by other users on some systems. The following are some of the notable bug fixes included in this release: For a list of bug fixes included in this release, see the JDK 6u111 Bug Fixes page. For more information, see Oracle Java SE Critical Patch Update Advisory. This release contains fixes for security vulnerabilities. Users wishing to revert to the old behavior can use the -sigalg option with the -certreq and -genkeypair keytool options. The default keytool signature algorithm has changed from SHA1withECDSA to SHA256withECDSA for EC based certificates. The default keytool signature algorithm has changed from SHA1withRSA to SHA256withRSA for RSA based certificates. The default cert fingerprint algorithm (emitted by keytool -list, -printcert, and other subcommands) now uses SHA-1 instead of MD5. Users wishing to revert to the old behavior can use the -keysize option with the -genkeypair keytool option. The default keysize has been increased to 2048 bits for RSA based keys. Modifications to keytool for this release
Users wishing to revert to the old behavior can use the -sigalg and -digestalg jarsigner options. The jarsigner default digest algorithm has been changed to SHA-256 from SHA1. The default jarsigner signature algorithm has changed from SHA1withECDSA to SHA256withECDSA for EC based keys. The default jarsigner signature algorithm has changed from SHA1withRSA to SHA256withRSA for RSA based keys. Modifications to jarsigner for this release By default, TLSv1.0 will remain the default enabled protocol on both Client and Server sides.Īs an example, TLSv1.1 can be enabled for use on SSL/TLS connections via SSLSocket/SSLEngine/SSLServerSocket APIs: TLS v1.1 is now a TLS protocol option with the release of JDK 6u111. Reversing this change is possible by removing MD5 from the security property in the curity file. Applications should upgrade or replace certificates that include an MD5-based digital signature. To prevent the use of X.509 certificates that include an MD5-based digital signature algorithm, MD5 has been added to the security property. MD5 must not be used for digital signatures where collision resistance is required. *MD5 now disabled for X509 Certificate validating* The following are some of the notable new features and changes in this release: JRE Security Baseline (Full Version String)įor more information about security baselines, see Deploying Java Applets With Family JRE Versions in Java Plug-in for Internet Explorer.
