Playframework 播放框架WS-execution异常[IOException:远程关闭[id:0x46，/localhost:port:>；远程主机名/远程IP地址：远程端口id]]

Play应用程序工作正常，突然停止工作。 我开始在浏览器中看到下面的异常

执行异常

[IOException:远程关闭[id:0x4628a18a，/ipaddress:端口：>远程主机名/远程ipaddress:远程端口]]

在我的应用程序中，我使用WS-api调用远程机器的restapi

下面是完整的垃圾堆

我完全不懂。正在寻找你的帮助。

提前谢谢。

我的错。发生这种情况是因为一个未处理的空指针异常。您是如何调试的？
