Currently, Hadoop requires java 5 for compiling documentation. The 
documentation program is Apache Forrest: http://forrest.apache.org/. And 
you also should have java 5, whose home should be given to ant.

So, you should run something like:

ant -Djava5.home=/path/to/java-5 -Dforrest.home=/path/to/forrest tar
