However, the build does not fail, so the emerge does not fail either. It's just missing some javadoc classes. I could reproduce this issue with both dev-java/blackdown-jdk-1.4.2.03-r16 and dev-java/sun-jdk-1.4.2.17 while dev-java/sun-jdk-1.5.0.14 seems to work. So a workaround would be this command: JAVA_PKG_FORCE_VM=sun-jdk-1.5 emerge ant-core The actual problem might be within the javadoc code itself, so I guess it might have to be fixed properly upstream. Still, the ebuild should deal with the issue, maybe depend on sun-jdk-1.5 if doc is used, maybe print a warning if files are missing from the generated documentation, I don't know.
I remember javadoc failing like this with some special tags should just dig out what it was and fix it in the javadoc sources.
Created attachment 182433 [details, diff] Switch lines, failonerror The cause seems to be @value tags after @since tags. This patch fixes the issue by switching some lines in question. It also adds failonerror to the javadoc tasks in build.xml.

Patch added. Sorry about the wait. It helps to ping us on IRC :)
Comitted upstream, so this patch can go as soon as it doesn't apply any more. https://issues.apache.org/bugzilla/show_bug.cgi?id=46731#c1 http://svn.apache.org/viewvc?view=rev&revision=775914
