 <h3>Requirements</h3>
 
 <p>The task needs Apache <a

+href="http://xml.apache.org/xalan-j/">Xalan 2.4.1+ or Xalan XSLTC</a>
 (JDK 1.4 contains a version of Xalan-J 2.x while JDK 1.5 ships with a
-version of XSLTC).  Versions prior to Ant 1.6.2 worked with Apache <a
-href="http://archive.apache.org/dist/xml/xalan-j/">Xalan
-1.2.2</a>, but as Xalan1 is no longer supported, we do not recommend
-this.  With Ant 1.6.2 we had to decide between supporting Xalan-J 1
-and XSLTC, since there was no way to support both at the same
-time.</p>
+version of XSLTC). Starting from JDK 1.4.2-01 it ships with a bundled
+Xalan-J 2.4.1+, meaning that JDK version prior to 1.4.2-01 won't work
+out of the box. The table below summarize the compatibility status.

-<p>If you want to use Xalan 1.2.2, the noframes report is still
-supposed to work.  If you want the frames support, copy the file
-junit-frames-xalan1.xsl from the Ant distribution's etc directory to a
-new directory, change its name to junit-frames.xsl and use the task's
-styledir attribute to point to it.  You will also need a compatible
-(older) version of Xerces.  as well as BSF(bsf.jar). Again, using
-Xalan 2 is simpler and supported.</p>
+<p>With Ant 1.6.2 we had to decide between supporting Xalan-J 1/Xalan J 2.4.1-
+and Xalan 2.4.1+/XSLTC, since there was no way to support both couples at the same
+time.</p>
