We have seen similar issues with this when we were experimenting with some
projects and upgrading to 2.8.2. The things to double check are:
1. That there are no duplicate jars from different versions of GWT, as
mentions by Thomas Broyer.
2. Delete any GWT generated folder such as the gwt-unitCache, and the
script outputs in the war folder and also any GWT generated files in the
temp folder.
3. If still running into problems, delete the Eclipse workspace .metadata
folder, re-setup the workspace and import the existing projects into the
cleaned workspace.
Due to GWT compilation caching, and Eclipse deployment caching, if files do
not change during the modification process, they can still reference the
the incorrect version of GWT, or the jars that are actually deployed to the
location where the Jetty server is run from by eclipse may not be updated.
