loadedFileUrls only contains the last one of urls with same file name
In XmlConfigurationProvider, the field `loadedFileUrls` contains the xml
files loaded. The loaded files will be checked if they are modified for
configuration reloading.
```java
public boolean needsReload() {
for (String url : loadedFileUrls) {
if (fileManager.fileNeedsReloading(url)) {
return true;
}
}
return false;
}
```
But in method `private List<Document> loadConfigurationFiles(String
fileName, Element includeElement) `, after the `while (urls.hasNext())` loop,
the variable `url` is assigned by the last one of urls with same file name.
So when `loadedFileUrls.add(url.toString());` is called in the `for
(Document doc : docs)` loop, only *THE LAST ONE* is added to loadedFileUrls.
I wrote a demo. I set `<constant name="struts.configuration.xml.reload"
value="true"/>
`. I wrote two configuration files: `struts-plugin.xml` and
`struts-biz.xml` in my web project. I use struts plugins such as
`struts-spring-plugin`, `struts-json-plugin` and so on.
The reloading works when I changed the file `struts-biz.xml` in my project.
But it does not work when I changed `struts-plugin.xml` in my project. I debug
XmlConfigurationProvider and see only the `struts-plugin.xml` in
struts-spring-plugin is contained in loadedFileUrls.
I tried to fix it by moving the `loadedFileUrls.add(url.toString());` into
the `while (urls.hasNext())` loop.
