Javadoc plugin causes site to fail

I don't reproduce this problem with the current maven-core (HEAD branch) and JDK 1.4.
But I have a problem if I use a JDK 1.3 (certainly due to the last jelly update) :
==================================================================
D:\Work\Dev\maven-plugins\html2xdoc>maven -Dmaven.javadoc.debug=true plugin:test

You have encountered an unknown error running Maven. Please help us to correct
this problem by following these simple steps:

• read the Maven FAQ at http://maven.apache.org/faq.html
• run the same command again with the '-e' parameter, eg maven -e jar
• search the maven-user archives for the error at
  http://nagoya.apache.org/eyebrowse/SummarizeList?listName=users@maven.apache.org
• post the output of maven -e to JIRA at
  http://jira.codehaus.org/BrowseProject.jspa?id=10030 (you must sign up first)
• run 'maven --info' and post the output as the environment to the bug above

I tried to build maven with the jdk 1.3 but I have the same problem

I tried with JDK1.4:

C:\source\maven-plugins\html2xdoc\src\plugin-test>set JAVA_HOME=c:\j2sdk1.4.2_03

C:\source\maven-plugins\html2xdoc\src\plugin-test>maven site

Arnaud, you're in the wrong directory to reproduce the problem.

You need to be in:

maven-plugins/html2xdoc/src/plugin-test

It works also for me.
But I think that it is because I use maven HEAD and not maven 1.0 branch.
I'll try with the 1.0 branch.
