       <ul>
         <li>
           <p>There is a known problem with the PDF generation tool (Apache's FOP) in that it doesn't allow for table structures with automatic column widths to be generated. Widths are uniformly distributed.</p>
         </li>
+        <li>People using java 5 will have to use this release with maven 1.1 or maven 1.0 with at the most the PDF plugin 2.2.X.</li>
         <li>
           <p>Due to several problems, it is actually impossible to reference the same file in different items in navigation.xml. You must define another navigation file (using the property <a href="properties.html">"maven.pdf.navigationFile"</a>) which you'll use only with the PDF plug-in. This navigation cannot define several items with the same href.</p>
