Source: How to set the Java version in JBoss or WildFlyĬonfiguring the JDK version in standalone mode is straightforward. Oracle JDK 1.8 and 11 – Open JDK 1.8 and 11 – IBM JDK 1.8 – Eclipse OpenJ911 Oracle JDK 1.8 and 11 – Open JDK 1.8 and 11 – IBM JDK 1.8 Oracle JDK 1.8 – Open JDK 1.8 – IBM JDK 1.8 In terms of JDK, here is the list of supported ones, in respect to each JBoss EAP 7 version and RHEL 7: JBoss EAP

In order to be running in a supported configuration, JBoss EAP must be running in one specific Technology Compatibility Kit (TCK) certified implementations and on one of the operating systems supported by that implementation. Much the same way, we recommend using the latter ( Java 17) for running WildFly 27. So you can mainly choose between Java 11 and Java 17.

WildFly version 27 drops support for Java 8.

On a balance, due to the amount of tests, it is recommended to use JDK 11.

WildFly versions up to 26 should run on the most recent long-term support release (LTS), i.e.

That being said, which is the recommended JDK version for WildFly ?There are two main options: You should therefore use any JDK in Min-Max range from the following table: WildFly Version

More specifically, each server release has a minimum requirement and also a “maximum” version, which is the last JDK version on which the application server has been tested. Since the early days of Java 9 development the WildFly team has worked to ensure that not only the WildFly code itself, but also the integrated libraries would all run well on the later generation JVMs.Ĭurrently the minimum version required to run a recent version of WildFly (15-21) is Java 8 (Oracle JDK or OpenJDK). The modularization of the JVM that began with Java 9 had a significant impact on a complex server like WildFly, particularly in the areas of classloading and reflection, both of which are extensively used. This tutorial discusses the recommended JDK versions to be used for WildFly and JBoss Enterprise Application Platform (EAP) and how to set the Java version for it.
