How to use pause and overprint together?

I want the items of a list (using itemize) to appear one after the other. I can use pause for the same and it works.

Now at the end of the list, I want to highlight only one of the items.

I thought I can use overprint with the list in the first part and the highlighted entry in the second part.

Here is the code for what I have tried.

\documentclass{beamer}


\begin{document}

\begin{frame}{Test Frame}
\begin{overprint}

\onslide<1>
\pause
\begin{itemize}
\item First line \pause
\item Second line \pause
\item Third line \pause
\end{itemize}

\onslide<2>
\pause
\begin{itemize}
\item \textcolor{blue}{First line}
\item Second line
\item Third line
\end{itemize}

\end{overprint}
\end{frame}

\end{document}

However, it gives me a compilation error:

! Extra }, or forgotten \endgroup.
\endminipage ...pagefalse \color@endgroup \egroup 
                                                  \expandafter \@iiiparbox \...
l.26 \end{frame}

! Class beamer Error: Overprints may not overlap.

I know of this work arounds: 1. Remove pauses (but i REALLY want them in there!) 2. Move the highlighted entry to the next frame -- which means create a new frame.

How can I achieve this without creating a new frame?
