I wonder if there's a way to generate an appropriate stream programmatically. Maybe something involving a pair of class loaders, A and B, which are children of the system class loader, but provide one additional class, a CompilationUnit subtype that isn't loaded in the system class loader. You write the stream using A and read it back using B. In addition to testing a class that doesn't exist in B, you could test slightly different versions of the same class in A & B and test for the incompatible class change. Not sure if it's worth all that trouble tho, just rambling here. http://gwt-code-reviews.appspot.com/1412801/ -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
