404重定向后无法访问request.forwardURI

Question

在我的grails应用程序中，我有一个自定义的"404“重定向。每当应用程序使用404时，它都会记录request.forwardURI并将用户重定向到404页面。但是在升级到wildfly-8.0.0(也尝试了8.1.0和9.0.0-alpha)之后，应用程序不会记录实际的URI( request.forwardURI)。

但是，在请求转储中，我看到了被请求的实际URI。我相信，这可能不是grails的问题，因为实际的请求记录在jboss-4和jboss-eap-6.2中。wildfly中的请求类是HttpServletRequestImpl，而在旧版本中是ApplicationHttpRequest。

我已经将war复制到了https://www.dropbox.com/sh/trzzmfp7pp5ut0f/AADBDczE4fx1oJGDUAw8FxAqa?dl=0中。请让我知道有没有其他方法可以让我得到实际的请求。

我能够通过另一种变通方法获得forwardURI。虽然，这不是获得forwardURI的理想方式，但它对我来说很有效。

forwardURI = request?.attributes.get("javax.servlet.error.request_uri")
