------------------------ it seems that trying to run any example make the application crash.

Support questions like this are better addressed at the Hub (JMonkeyEngine’s Discourse forum): https://hub.jmonkeyengine.org/

The “Inconsistency detected” error indicates that OpenJDK was compiled with a version of the C runtime library that’s incompatible with one of the native libraries in your application. jme3-lwjgl is a likely candidate, but there are several other possibilities. It’s more of an issue with OpenJDK than with JMonkeyEngine.

On my own Linux system, I worked around this issue by installing Temurin and setting the JAVA_HOME environment variable in my .bashrc to point to the install directory export JAVA_HOME=/usr/lib/jvm/Temurin/jdk-11.0.14.1+1

Thanks for the replies. My linux configuration is quite old and maybe it’s a problem of my hardware. I tryed on a new laptop in windows and it worked, even if some examples have missing assets and won’t start, but the majority of it is working. Thanks for the suggestions.

Download jdk from oracle website, extract, then to run, locate its java executable file :

/home/Downloads/jdk-1.8.0/bin/java -jar MyGame.jar

and it will work !
