		 * We want to serve up resources from this directory, using a wildcard.
		 * The way the PathResourceResolver.isResourceUnderLocation(resource,
		 * location) checks for a valid Resource treats wildcards as a specific
		 * file name and doesn't get a match.
		 *
		 * The fix is as easy as getting rid of the wildcards, but there are
		 * other times when wildcards would be nice to have in your resource
		 * handling paths.
		 *
		 * The bug/regression was added in 4.1.x (can't find exactly which
		 * release it was included in) as part of a refactoring of the
		 * PathResourceResolver (splitting it off from
		 * ResourceHttpRequestHandler):
