Arthur, One of the things I commonly do when writing "non-GWT-specific" code is to isolate GWT-specific code behind an abstract class or interface and then inject different versions depending on application. One good example is java.text.SimpleDateFormat vs GWT's DateTimeFormat. I have a DateFormatter interface with parse and format methods, and a DateFormatterFactory that makes instances of DateFormatters (from format strings). You can then inject manually (or with something like GIN) versions of DateFormatterFactory, or mocked versions. This may not work for everyone, but in my case, I have to do it, because certain environments (like Android) are very finicky about loading the GWT classes. For example, the Dalvik verifier, upon seeing a method which references the GWT URL class, would try to load it, and even if it were present, it might cause problems due to the native methods, but sometimes you end up with some verification failure far down the execution path because of transitivity (e.g. Foo references URL which references another GWT class, which references another, etc)
