LaTeX lstlisting not highlighting keywords when basic style is ttfamily

Question

Hello,

I'm working on a LaTeX document and using lstlisting to display my Java source code. My setup looks like this:

\lstset{
 basicstyle=\ttfamily,
 keywordstyle=\bfseries,
 language=Java,
 frame=single,
 aboveskip=11pt,
 belowskip=11pt,
 breaklines=true,
 breakatwhitespace=false,
 showspaces=false,
 showstringspaces=false

}

The keywords are not highlighted bold when using ttfamily, but if I use small or don't specify the basic style, they're highlighted fine.

What am I missing?

The default font in LaTeX, Computer Modern, does not provide a bold version of the teletype family. You can install this as the bold-extra package; see this FAQ entry for details.
