 Yes I know. This is true for java applications that you launch from the
 terminal/shell. But I need to "link" the JVM with a macOS bundled java
 application (Arduino.app in the `/Applications` folder). As far as I could
 see the `JAVA_HOME` shell variable set in the Bash profile configuration
 file doesn't affect the .app application.

 Furthermore as you can see from the third attached image, the .app file
 contains already the entire `openjdk8` JRE.
