However, this time, it’s bigger and better. New in Java 11Įach release of Java introduces a number of new features. Before answering the question: “when will Java 11 replace Java 8 as the default version of Java?,” let us first get to know Java 11 better.
OPENJDK VS ORACLE JDK WINDOWS
Though JDK versions prior to Java 8 are still supported by organizations on a commercial basis, it is highly recommended to uninstall pre-Java 8, especially from Windows computers. This is because it was a rapid release version, like Java 9, which contained support that has also been removed. With the release of Java 11, support for Java 10 ended. In its place, the OpenJDK community will provide long-term support, most probably in the form of AdoptOpenJDK. What’s interesting with Java 11, aside from all the added, removed, and deprecated features, is that it won’t be supported by Oracle. For non-commercial use, the same is scheduled at an unspecified date in December of 2020. The end of public updates for Java 8 is scheduled for January of 2019 for commercial use. He proposed to replace the two-year schedule with a twice-a-year release cycle.Īt the moment, Java 8 and Java 11 are the LTS (long-term support) versions. This is in line with the proposal made by Mark Reinhold, Chief Architect of the Java platform, back in 2017. The release of Java 11 followed Java 10 only by 6 months.
Ever since JDK Beta made its debut back in 1995, there has been continuous development of the platform for this high-level, general-purpose programming language. You have to do all this in the same RUN command, chaining with & to avoid adding layers where you won't remove size by removing files from previous layer.The latest version of the Java Development Kit, Java 11, is out. jar files are already compressed, the tar.gz is just there to "package" them.
tar.gz file which is roughly the same size as the resulting directory as. One thing you should do in your dockerfile while installing oracle jdk is to remove the downloaded. You can without problem remove missoncontrol on a server, I assume you can get rid of visualvm also, you'll have to check if you need something in this lib directory, but I can't tell without knowing your app. There's two *src.zip which can be removed, they won't be of use, and as you can see the lib directory is half the size and within it you have a bunch of things you don't really need: /usr/lib/jvm/jdk1.8.0_101$ du -hs lib/* By "lazyness" due to the complexity to list every needed dependency no one strip down to the necessary libraries only, but that is the way to go if you wish to reduce the installed size to strict minimum.Ī more usable way could be strip off some of the installed things which are taking a lot of space: /usr/lib/jvm/jdk1.8.0_101$ du -hs * JDK is the acronym of Java Development Kit, JRE is the one for Java Runtime Engine.
OPENJDK VS ORACLE JDK FULL
As docker is not an operating system, no there's no JDK for docker.Īs I understand your question, it's that a full JDK is too large for your wishes, in this case you may try switching to just the JRE and include only necessary libraries.
