LaTeX uses the first font dimension in the italic correction code. This number must be strictly positive for italic fonts.

\documentclass{article}
\begin{document}
\textit{\the\fontdimen1\font}
\end{document}

compiled with pdfLaTeX results in 0.25pt, but

\documentclass{article}
\usepackage{luaotfload}
\usepackage{lmodern}
\usepackage[EU2]{fontenc}
\begin{document}
\textit{\the\fontdimen1\font}
\end{document}

compiled with LuaLaTeX results in 0.0pt.
