> Using Commons Configuration with JBoss 5 presents problems when storing files
> in the JBoss directories and referencing them with relative paths. This
> applies to configuration files stored in the traditional spot for JBoss
> configuration, like JBOSS_HOME/server/default/conf/. More specifically, when
> FileChangedReloadingStrategy tries to resolve the file path it gets a
> vfsfile: URL from the JBoss-modified context classloader, that it can't
> parse. The following patch adds support for this URL scheme by fixing the
> resource URL to avoid VFS, and allows Commons Configuration to properly
> recognize file modifications in the file system.
