LGTM with a couple of questions.
http://gwt-code-reviews.appspot.com/119803/diff/1/2 File user/src/com/google/gwt/core/client/Scheduler.java (right): http://gwt-code-reviews.appspot.com/119803/diff/1/2#newcode70 Line 70: unimplemented(); Is it better to have this fail at runtime than to require people to update their custom schedulers (by making these abstract)? http://gwt-code-reviews.appspot.com/119803/diff/1/7 File user/test/com/google/gwt/core/client/impl/SchedulerImplTest.java (right): http://gwt-code-reviews.appspot.com/119803/diff/1/7#newcode87 Line 87: @DoNotRunWith(Platform.HtmlUnit) Would it be useful to add a comment explaining why HtmlUnit can't be used? Otherwise, it will be hard to know when this should be removed. Likewise with the others. http://gwt-code-reviews.appspot.com/119803 -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
