+<h4>Problems with pre-installed ANT on newer Linux distros</h4>
+
+<p>
+Notice that pre-installed ANT version (i.e. ANT versions installed with the
+corresponding system package manager) may cause problems in conjunction with
+our bootstrap JDK. This is because they use various scripts from the
+<a href="http://www.jpackage.org/">jpackage</a> project to locate specific Java
+libraries and jar files. These scripts (in particular 
+<code>set_jvm_dirs()</code>
+in <code>/usr/share/java-utils/java-functions</code>) expect that executing
+"<code>java -fullversion</code>" will return a string starting with "java" but
+our OpenJDK port returns a string starting with "openjdk" instead.
+</p>
+
+<p>
+The problem can be easily solved by either editing the regular expressions
+which parse the version string
+in <code>/usr/share/java-utils/java-functions</code> (or the respective file of
+your Linux distribution) or by installing a plain version of ANT
+from <a href="http://ant.apache.org/bindownload.cgi">http://ant.apache.org/bindownload.cgi</a>
+and passing its installation directory to the build via
+the <code>ANT_HOME</code> environment variable.
