ClassCastException of same object type

I have ObjectDB partially working with my project. At the moment it seems to be saving objects and retrieving objects ok in the main project. However, when I make a plugin for the project, the new objects are persisted but not retrieved. I get the following error: java.lang.ClassCastException: org.sportscoring.ssv.xc.core.XCCompetitorCount cannot be cast to org.sportscoring.ssv.xc.core.XCCompetitorCount ...
