OK. Can you open a JIRA issue in the war plugin? The version you're using is
not JDK 1.4 compatible, but I simply guess that the developer was not aware
of it.

Background: XStream is a small library converting objects to XML and back.
The developers of the war plugin used it to convert somewhere between this
DependencyInfo and XML. However, this type has a final field "dependency".
Since JDK 5 it is possible to write into final fields using reflection (see
Javadoc), but it is simply not possible with JDK 1.4. For JDK 1.4 support
the field may not be declared final.
