[jdom-interest] Document getter/setter not the same (collection vs List)

[Jason Hunter]

Well, here's the source of the complaint:

In Document.java:

   public List getContent() { }
   public Document setContent(Collection newContent) { }

The JDOM programming contract is you can pass in any old Collection type 
as content but JDOM promises on access to return a specific type of 
Collection, a List.  NetBeans seems to have a problem with this.  It 
must be making some wrong assumptions that Content is a property, 
probably in the hidden magic it performs on the method since it's marked 
@WebMethod.
