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

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
