We’ve assessed all JDK builds using the following criteria:

#OPENJDK VS ORACLE JDK FULL#

Here is the full list of JDK builds we’ve researched: The most popular and famous builds are distributed by Red Hat, Azul and community-led Adopt OpenJDK.

If an organization produces an OpenJDK build that passes the TCK then that build can be described as “Java SE compatible”. This certification is run by the Java Community Process, which provides a Technology Compatibility Kit (TCK or JCK as Java). So, Oracle created a certification process that should be used to ensure the build is valid. It is hosted in Mercurial at OpenJDK.Īnyone can take the source code, produce a build, and post it.

JDK buildsīasically, there is only one set of source code for the JDK. Most of them have different support models (free and paid for), and different attitudes toward providing updates for multiple Java versions.Īs Oracle is not the only vendor in this game, it’s time to look beyond their JDK.ĭevexperts is happy to share with you the results of our research. So, to get the JPL dependency via GitHub packages we need to do as follows.The changes to the Oracle licenses forced us to look for other JDK vendors.

To download and install packages from a repository, your personal access token (classic) must have the read:packages scope, and your user account must have read permission.Indeed, the GitHub documentation explains: The drawback as of today (June 2020 and revisited Dec 2022) is that one as to have authenticate to GitHub (via TOKEN) to even just have read access to a package from GitHub see this post.

The JPL JAR artifact can also be satisfied/obtained directly from the GitHub Packaging system, without the need to go via JitPack. Prolog packages-jpl V8.3.2 įor example, the V8.3.2 version corresponds to a tag in the repo: The first step is to add the following repository to the POM’s application: JitPack will clone a Maven project from GitHub (in this case JPL’s repo), compile it, and serve the JAR artifacts. JitPack is a service that can serve maven artifacts by accessing GitHub repositores. One can then grab the latest JAR file from the packages section in JPL repo or even better add the JPL as a Maven dependency of the Java application by including two repositories: GitHub Packages or JitPack (recommended as no token-based authorization is needed). While the C Native library libjpl.so and Prolog API jpl.pl do not change much, the Java API provided in jpl.jar does tend to change and be updated more frequently to provide a better Prolog access from Java.īecause of this one may want to use a particular SWIPL standard install, like the latest 8.2.0 from the Ubuntu PPA, but use a more updated Java API jpl.jar that the one coming with such release. AdoptOpenJDK 11 (Hotspot), AdoptOpenJDK 11 (OpenJ9), and OracleJDK 13 (Hotspot) see here.On the other hand, errors have been reported when using: The new Java can be obtained from AdaptOpenJDK. However, others have reported success with OpenJDK 8 with OpenJ9 as JVM (using the Hotspot may yield a fatal error). The current guide/documentation has been produced using the Oracle Java SE 8. The changes are fairly complex but a good summary and explanation of impact can be found here Note there has been some changes in Licenses from Java SE 11. One can use Oracle JDK or OpenJDK check a comparison here. Next versions of JPL will probably use 1.8+ language features. The source version for JPL 7.6.1 is Java 1.7, so no advanced features like lambdas are used.
