I believe there is a new warning message that was added to
javadoc for Merlin:

javadoc: warning - Method org.xml.sax.helpers.XMLReaderAdapter.skippedEntity
        declares that it throws org.xml.sax.SAXException,
        but does not document it.

The JDK puts out hundreds of these warnings. Relatively speaking,
this is not a very important warning, and it drowns out other
more important warnings.

I believe we should probably turn off this warning and move the
check to DocCheck doclet (or create another warning level in javadoc
for it).

The reason is because this warning is inconsistent with the other
warnings. We do not produce warnings that the parameters or
return values are not documented, so I see no need to warn about
Exceptions.

If we want to add more error-checking to Javadoc, I suggest
we consider introducing warning levels and the ability to turn them
on and off.
