You can see the same problem but with hibernate here<http://code.google.com/intl/es/webtoolkit/articles/using_gwt_with_hibernate.html>. In this page show some strategies to resolve the problem. In my case I don't adopt this strategies. I do a filter. In Pro Web 2.0<http://books.google.com/books?id=OG816JSZYVcC&pg=PA159&lpg=PA159&dq=gwt+hibernate+filter&source=bl&ots=BM1JxFq0h9&sig=gTKoh1ZBWs26d5vjRi-7CP4fo20&hl=es&ei=R0OPTu_4GZC1hAfXmc32Dw&sa=X&oi=book_result&ct=result&resnum=7&ved=0CF0Q6AEwBg#v=onepage&q=gwt%20hibernate%20filter&f=false>explain the use of a *filter*. A class that, in your case, for example convert org.datanucleus.sco.backed.List in java.util.List. This filter intercept the classes before send to client. Here <https://bitbucket.org/gardellajuanpablo/gwt-sample/src/8aba86d82778/src/main/java/com/foo/server/rpc/hibernate/HibernateFilter.java>you have an example of a Hibernate filter compatible with GWT 2.4.0 and how integrate in a sample project.
