Replacing "&amp;" with "and" in the text of the docs fixes PDF generation on my machine. Otherwise "mvn clean site" does not work for me. This is odd as others on the ML report that PDF generation works for them. Before this, I would get:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-pdf-plugin:1.2:pdf (pdf) on project log4j: Error during document generation: Error creating PDF from C:\vcs\svn\apache\log4j2\trunk\target\pdf\log4j-users-guide.fo:23:9
