The Javadoc build spits out a lot of complaints! I was able to quite a great many of these complaints merely by supplying a classpath on the Javadoc build. In addition, I fixed package-summary links that were broken. (I broke some of them, I think.)
Attached is a patch.
NO CODE is modified in this patch. Files touched are:
In build.xml, I replaced hard tabs with spaces, since hard tabs were not universally used and the occasional use interfered with the indentation. If this is not desired, let me know and I'll reissue the patch.
