Java AppEngine上Jersey的NoClassDefFoundError（AsyncContext）

我正在AppEngine（Java）上运行我的服务器应用程序，使用Jersey（2.10.1）。我的应用程序在登台服务器上运行良好，在部署到生产环境后工作正常

几小时后，我们开始看到请求失败，并记录了AsyncContext的NoClassDefFoundError（请参阅下面的stacktrace）。这几乎发生在我的所有Jersey服务中，无论它们返回JSON还是重定向。AppEngine仍然只支持Servlet2.5API，但Jersey 2.10应该可以

幸运/不幸的是，重新启动appengine实例有帮助。有什么建议可以解释是什么原因造成的吗

看一看，然后@RafaelZeffa谢谢。不幸的是，除非我遗漏了什么，否则这个答案（两个链接都是相同的）建议升级到servlet-3.0。这在Google AppEngine上目前是不可能的。对不起，另一个链接是它，支持servlet 3.0的人也很多：
