更新到java 6u31后，DevServer失败 [英] DevServer fails after updating to java 6u31

问题描述

这是我收到的错误。当我恢复使用6u30时，它工作正常。

This is the error I recieve. When I revert to using 6u30, it works fine. AppEngine must be updated now to fix this bug.

推荐答案

这是一个已知的错误： http://code.google.com/p/googleappengine/issues/detail?id=6928

This is a known bug: http://code.google.com/p/googleappengine/issues/detail?id=6928

解决方法是添加这条线到你的运行配置：

Workaround is to add this line to your run config:

-Dappengine.user.timezone=UTC

有些人必须这样做：

For some people it must be:

-Dappengine.user.timezone.impl=UTC

似乎后者在包含GWT的情况下工作;如果您不使用GWT和GAE，请使用前者。

Seems that the latter works if GWT is included; if you don't use GWT along with GAE, then use the former.
