[Tex/LaTex] equal contribution using thanks with llncs class

footnoteslncs

I am trying to add equal contribution footnote using the \thanks keyword.

\documentclass{llncs}

\usepackage{hyperref}

\begin{document}
\title{Some Title}

\author{Author1 \thanks{equal contribution} \and Author2 \footnotemark[1] \and Author3}
\institute{\email{email1, email2, email3} \\ Institute}
\maketitle

\end{document}

This gives me an error,

! Use of \@xfootnotenext does not match its
definition

Any work around ?.

It seems that \footnotemark cannot be used in the \author field for llncs. Here's a workaround:

\documentclass{llncs}

\usepackage{hyperref}

\makeatletter
\newcommand{\printfnsymbol}[1]{%
  \textsuperscript{\@fnsymbol{#1}}%
}
\makeatother

\begin{document}
\title{Some Title}

\author{Author1\thanks{equal contribution}
\and Author2\printfnsymbol{1} \and Author3}
\institute{\email{email1, email2, email3} \\ Institute}
\maketitle

\end{document}
