LGTM. I'm a bit hesitant about "die" == UnableToCompleteException in TreeLogger in general, but have no issues with it here.
(As an example, I'm not sure that's the right exception to throw for an issue early in starting hosted mode shell, although it's maybe not clearly the wrong exception either.) http://gwt-code-reviews.appspot.com/72805 --~--~---------~--~----~------------~-------~--~----~ http://groups.google.com/group/Google-Web-Toolkit-Contributors -~----------~----~----~----~------~----~------~--~---
