@tobiasstarkwayve Thanks for the contribution. Everything seems to be in order, but the clang-format preflight check complains. In the root dir of the repo, there is already a .clang-format file. Could you please format the file with your IDE? It should work out of the box with any clang-format extension.

You must also sign the Eclipse contribution agreement (https://www.eclipse.org/legal/ECA.php) using the email address you used for your commit message.

As soon as this is done, we can merge the PR.

Done. I actually signed the ECA yesterday already, but I think it took some time to propagate the information (or pushing a new commit forced it to re-evaluate). Either way, the box is green now :-)
