I suspect the upcoming support will be a better fit when it comes, and I 
can live with my workaround until then.

Any chance that we could add a "quiet" flag to it that would keep it 
from barfing if the fileset is empty?  I can get around it either way, 
but it would be nice to have it elegant for my application.

E.g.

<property name="jar.extra.zip1" value="first.jar"/>
<property name="jar.extra.zip2" />

<fileset id=zipfiles>
   <file name="jar.extra.zip1"/>
   <file name="jar.extra.zip2"/>
</fileset>

<jar
   jarfile="product.jar"
   basedir="${compile.classes}"
   <zipfileset src=zipfiles quiet="true"/>
</jar>

should work, as filesets are allowed to have empty things in them, 
IIRC.  Will it fail silently if someone sends an empty fileset, and if 
not, is a flag to request that appropriate?
