java - 处理请求时发生异常 : java.net.URISyntaxException:绝对 URI 中的相对路径

Question

刚刚检查了我开发的系统的WildFly日志，发现了以下错误:

2017-05-03 08:48:08,575 ERROR [io.undertow.request] (default task-4) UT005001: An exception occurred processing the request: java.net.URISyntaxException: Relative path in absolute URI: https://www.google.com:443http://www.google.com/

除了 https://www.google.com:443http://www.google.com/ 还有 https://testp3.pospr.waw.pl:443http://testp3.pospr.waw.pl/testproxy.php 和 https://www.baidu.com:443http://www.baidu.com/cache/global/img/gs.gif 。

有人知道可能是什么问题吗？

编辑:在此日志发生几个小时后，出现了 java.lang.OutOfMemoryError: Java heap space 并且系统崩溃了，需要重新启动 WildFly 才能再次启动系统。我无法确定崩溃是否与此错误有关。

我的猜测是有人正在向您发送以下形式的 URL:

http://yoursite.com/https://www.google.com:443http://www.google.com/

尝试从浏览器发送该 URL，看看是否收到类似的错误。
