I created http://gwt-code-reviews.appspot.com/1721803/ to update the API checker config file. Its a fairly simple process, but since we only do it 2-3 times per year, we always forget how.
I'll submit your change after the API Checker config file is updated. We should just need to add these lines to it: java.lang.Boolean::FALSE FINAL_ADDED java.lang.Boolean::TRUE FINAL_ADDED http://gwt-code-reviews.appspot.com/1710804/ -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
