GWT 2.3升级后的RPC错误

升级到GWT 2.3后,我的一些RPC服务不再有效
失败了“响应无法反序列化”.好像
发生在返回使用Date的对象的服务上
使用@Temporal(TemporalType.TIMESTAMP)注释的对象.一世
使用Gilead 1.3.2和Hibernate 3.6,我对GWT 2.2没有任何问题.
知道会发生什么,或者如何开始调试？

这是堆栈跟踪：

我有类似的问题–Gilead 1.3.1,Hibernate. Exception也在Timestamp字段上抱怨.

这是我在吉利德网站上发现的东西：

“与Gilead一起发布的Timestamp_FieldSerializer与明显在GWT 2.2或2.3中引入的一个冲突”

http://sourceforge.net/tracker/index.php?func=detail&aid=3285026&group_id=239931&atid=1111398

“详细信息”部分的结尾提示了简单的修复,但是,我还没有尝试过.
