the starting wrapper /usr/bin/arduino is simply using 'java' as the binary name to call the JRE binary but does not check if the binary in the path is usable or suitable. ----%<---- > JAVA=java > if [ -x "$APPDIR/java/bin/java" ]; then > JAVA=$APPDIR/java/bin/java > fi ---->%---- Sven, you could please check where /u/b/java is pointing to? It should look like this. > $ ls -la /usr/bin/java > lrwxrwxrwx 1 root root 22 19. Jun 2017 /usr/bin/java -> > /etc/alternatives/java > $ ls -la /etc/alternatives/java > lrwxrwxrwx 1 root root 43 8. Nov 2018 /etc/alternatives/java -> > /usr/lib/jvm/java-11-openjdk-amd64/bin/java I've recently discovered similar problems elsewhere and I needed to reinstall the openjdk packages. So it's possible that some symlinking isn't correct. It's also possible that something is changing the variable JAVA_OPTIONS that is finally used in the wrapper. You can simply add a line like this right before the last line in the wrapper script. > JAVA_OPTIONS+=("-splash:$APPDIR/lib/splash.png") > fi > > +echo "Using JAVA_OPTIONS: $JAVA_OPTIONS" > "$JAVA" "${JAVA_OPTIONS[@]}" processing.app.Base "$@" Then please call arduino again from CLI. -- Regards Carsten
