That's easy, too - you just have to download a tarball and extract it somewhere. Nevertheless, be sure to check what Java version that actually installs. This is very simple, you just need the following package. In fact, the JVM fails to start and complains about unrecognized options. At that time, it was a commercial feature of Oracle JDK, but OpenJDK 11 comes with it.Īs a consequence, installing openjdk-11-jdk doesn't allow applications to be instrumented with JFR, as the JVM options used to enable it simply aren't getting recognized by OpenJDK 10. OpenJDK 10 doesn't contain the flight recorder.
There's one area tiny though where there's a significant difference between 10 and 11- Flight Recorder is now open source.
#Install openjdk 11 ubuntu upgrade#
That's a fairly good reasoning and perhaps an apt-get upgrade wouldn't screw things up that badly when OpenJDK's version gets bumped up from 10 to 11. This choice was based on that assumption that there is a much smaller interface delta between releases 10 and 11 than it would be between 8 and 11. Although version 10 is a non-LTS release, they've packaged it as openjdk-11-jdk until OpenJDK 11 goes GA. The Ubuntu Foundation Team made an SRU exception for OpenJDK. After having it installed on Ubuntu 18.04 (Bionic Beaver), which comes with a package named openjdk-11-jdk, to my surprise, that was still part of an earlier version (Java 10). As this is the first LTS release after version 8, it's been a long time coming. OpenJDK 11 was released on September 25, 2018.
