Red Hat expects to deliver 4 updates per year and timely security fixes for the OpenJDK 8 and 11 distributions.

Support duration is 6 years from the time that a major version of OpenJDK is first introduced in the particular version of Red Hat Enterprise Linux, or until the retirement date of the underlying version of Red Hat Enterprise Linux, whichever comes first. Red Hat provides long-term support for OpenJDK versions 7, 8, and 11. Is there a reason for it The Java Development Kit (JDK) is part of the Java SE Product, there are other parts as well, but you can treat them as the same thing for development purposes. But why to have two names It just make it confusing. It is useful for understanding application behavior such as memory leaks, deadlock, and much more. Java SE (Standard Edition) is the product name for the JDK. OpenJDK includes Mission Control 1 which is a tool suite for managing, monitoring, profiling, and troubleshooting Java applications. OpenJDK is tightly integrated with Red Hat Enterprise Linux and is supported on Windows.

A standalone Windows subscription is also available for purchase. OpenJDK support is included in Red Hat Enterprise Linux®, Red Hat Middleware, and Red Hat Application Runtimes 8 Appendix 8.1 Table of Abbreviations AbbreviationĨ.2 Glossary 8.Red Hat is a member of the OpenJDK Governing Board and is the second largest contributor (behind Oracle). Other than the license, I could not find any significant differences between OpenJDK 12 and Oracle JDK 12. The announcement that OpenJDK and Oracle JDK are converging turns out to be true. For example, some classes might have symbols which are present in only one of the JDKs and not the other. There might be differences which are one level deeper than the level that I've analyzed so far. jdk.jdeps ( man1/javap.1, man1/jdeprscan.1, man1/jdeps.1).jdk.jartool ( man1/jar.1, man1/jarsigner.1).jdk.compiler ( man1/javac.1, man1/serialver.1) Eine bersicht aller verfgbaren JDK-Portierungen sowie die neueste Java Version findet man auf der Webseite von ORACLE.jdk.accessibility ( man1/jaccessinspector.1, man1/jaccesswalker.1).java.rmi ( man1/rmid.1, man1/rmiregistry.1).java.base ( man1/java.1, man1/keytool.1).Some modules contain man pages, which are only present in Oracle JDK 12: Without verification, I would assume that these classes, especially, are related to verifying the subscription for the Oracle JDK.

The java.base module of Oracle JDK 12 contains a few classes which are not part of OpenJDK 12: Listing 6-1: Comparing the modules of OpenJDK 12 and Oracle JDK 12 6.1 Modules with different classes: java.base for i in openjdk-12/jmods/*.jmod do mod=$(basename $i) echo $mod diff -I 'legal.*' <(jar tf openjdk-12/jmods/$mod | sort) <(jar tf oracle-jdk-12/jmods/$mod | sort) echo done The modules themselves are almost identical.

OpenJDK 12 and Oracle JDK 12 contain exactly the same list of modules. The header files in OpenJDK are GPL2, the header files in Oracle JDK refer to the proprietary license.

The header files differ in the license terms. The technical contents of the header files in the include/ directory are identical. The legal files differ, obviously, because of the different license terms and conditions. That's weird, and this must be a bug in OpenJDK. Listing 2-1: Comparing the release files of OpenJDK 12 and Oracle JDK 12 3 Man Pages This can be seen by looking at the differences between the two implementation's release files: diff openjdk-12/release oracle-jdk-12/release The OpenJDK 12 and Oracle JDK 12 are based on the same commit b67884871b5f in Mercurial.
