Answer 1

GWT 2.2的方式，打破了很多的第三方庫的向後兼容。在這種情況下，看起來您正在使用Restlet for GWT。

在這些情況下，您唯一的直接補救辦法是查看庫的來源並自行構建。由於這往往是複雜或不切實際的，你的下一個最好的選擇是等待第三方發佈一個GWT-2.2兼容版本的庫。

特別是在Restlet的情況下，您應該堅持使用GWT 2.1，直到Restlet 2.1 M3發佈「next week」。

Answer 2

Restlet 2.1 M3剛剛發佈，包括對GWT 2.2的支持。感謝您的耐心等待 http://blog.noelios.com/2011/03/31/restlet-framework-2-1-m3-and-2-0-6-released/
