thanks Denis for the analysis

I think the culprit is http://jira.codehaus.org/browse/MPLUGIN-227

and javadoc plugin is just intolerant at this case where there is some code in 
"unnamed" package: not a regression, just a case that wasn't seen in real 
world before the bug in plugin tools

I just created https://jira.codehaus.org/browse/MJAVADOC-354 which I should fix 
immediately

Regards,

Hervé
