> Exception throw for empty "Dependencies:" header in MANIFEST.MF.
> This is a perfectly well-formed header and should have the same meaning as if the header does not exist.
> By all means emit a warning explaining which JAR the MANIFEST.MF is in, the header name and that the value is an empty string and this is not allow (due to some spec/rule you cite).
> But don't fail a deployment from starting.
> Sometimes headers are not going to be perfect from dependent JARs you have little control over.  You don't want to make the user do extra work of repacking/fixing those JAR just to get them to deploy on JBoss AS.
> If the empty header has a special meaning then I suggest you use a keyword token instead.  Like you do for "export", "services" and "optional".
