Version-Release number of selected component (if applicable):

2.1

How reproducible:

100%

Steps to Reproduce:
1. Insert a programlisting into your document.  XML/Java: doesn't matter.
2. Set the programlisting opening tag as "<programlisting language="Java" linenumbering="numbered">.
3. Publish to any format.
  
Actual results:

When you publish the document, it fails with the following error.
No numberLines function available.

Expected results:

Line numbers are inserted into the programlisting to help users refer to parts of the code.

Additional info:

This ticket results from a Tech Review of the JBoss Security Guide.  The reviewer has asked for line numbers.  I will implement a work around for this by splitting up the code block (it's rather large) into chunks so readers can read about the relevant section below the sample.
