此错误跟踪正在污染我的日志，我在 SA 上找不到或者是什么原因导致它：

这是针对在 Payara micro 5.2021.2 上运行的带有 JSF 2.3（Faces）的 JakartaEE 应用程序。如果这有任何相关性，以下是将流量重定向到应用程序的 nginx 配置部分：

看起来灰熊正试图从Host请求的标头中获取主机名。由于 HTTP 1.1Host需要标头，但如果Host标头设置为空名称，则 Grizzly 无法获取名称并引发异常。

请求标Host头由 HTTP 客户端设置。但是，即使Host标头存在但由于某种原因其值为空，也会抛出异常。

灰熊代码：抛出异常的代码

根据Grizzly 的 Javadocs，您可以通过调用该方法来设置默认主机名setDefaultHostName(String defaultHostName)，但实例中的 MapperHttpHanderChain实例不会公开。实例中设置HttpHanderChain的默认值设置为 "localhost"。Mapper
