Sure, with "you" I meant more that doxygen should stop to use tabu.

No probably it is something else. But as long as your failing code
is based on code loading lots of large, in parts broken packages it
is quite improbable that someone will debug it. 

But I just tested with miktex (which has a newer luatex) and there
it works, so it looks as if the problem is resolved and will work in
the next texlive (I would guess that it is the problem discovered
here https://github.com/latex3/luaotfload/issues/241, as removing
the discretionary helps in your example too).

Side remark: As you mention characters: Consider to replace the font
setup with something suitable for lualatex. 

\usepackage[T1]{fontenc}, helvet and courier should not be used. Use
fontspec instead to setup the fonts.

And remove the pdftex option from hyperref as you obviously don't
use pdftex.
