[jboss-dev] Re: metadata empty lists are now null

[Scott M Stark]

Its the behavior of the binding layer with jaxb. The question is whether
emtpy elements would be output as empty xml elements vs null elements
not being output. That the java for loop syntax does not check for null
Iterables makes this much more painful than it should be.
