There are two definitions for AstractObservableList.add(Object) in 
org.eclipse.core.databinding.observable.list.AstractObservableList.

Most of the rest of the problems are the same issue, just for different 
functions.

I would guess that you built one version, updated, and built again 
without first cleaning, and somehow got duplicate object files somewhere.

There are also some undefined symbols. If you haven't modified your dwt 
working copy, I'd delete it and install from scratch.
