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.

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

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

Then please call arduino again from CLI.
