The problem with your code is that java.lang.Class *cannot* be transmitted over GWT RPC. See: http://groups.google.com/group/Google-Web-Toolkit/browse_thread/thread/bb44013e7a72a92c for a full description of the issue.
On a side note, you might want to reconsider doing something like: <T extends IsSerializable, Serializable> List<T> get(...) This will force the GWT compiler to generate code to serialize/ unserialize every type that implements Serializable, which will bloat your application as there are many such types. You're better off constraining the types used in your RPC interfaces to what actually will be used.
