When URL escaped values are used as part of a URL matched by the UriTemplateFilter, the filter does not decode those values. In the example config posted, when http://localhost:14444/echo/%25 is passed in, the output is %25, not %. Although you could add a URL decoding transformer after the filter step to get the desired result for the payload, doing the same for properties would be more cumbersome. It seems like the filter should be handling this itself.
