[jdom-interest] JDom and Java5

[Mattias Jiderhamn]

Now I got the updated JAR and it works fine.

Although it seems return type List<?> requires an explicit cast whereas 
List just issues a warning when assigned to List<Element>. So if you 
want to minimize the code changes needed you should probably switch to 
just List.
