I am sorry, but the provided zip archive seems to be empty. 
Could you please check and reattach it or even send it to me via email?

Thank you
Mario

Yeah I forgot to use -r on the zip command.

It seams you forgot to use the by() method to create the group condition. It 
should
work as it follows:

Group<FeldError> groupedByFeld = group(feldErrors, 
by(on(FeldError.class).getFeld()));

Please confirm that it works in that way so I can close this issue.

Thank you
Mario

Confirmed that it does work correctly when by is used.
User error.
Thank you.
