Google translate tells me this is your question: "Why is your J8 - 40way different from the official one?" ;-)

"Official numbering of the header" = BCM numbering
Pi4J V1 under the hood uses the WiringPi library which has indeed a different numbering.

On this page this is explained in more detail: https://pi4j.com/getting-started/understanding-the-pins/ and in this image you get both BCM and WiringPi side-by-side
