Description

UTF-8 encoded characters in a json response from a REST endpoint are being altered when accessing the endpoint behind the knox gateway. When accessing these endpoints directly the expected response is received.

Here is a comparison of the responses received when accessing the endpoints using curl:

Output when NOT accessed through knox gateway (Expected Output)
HTTP/1.1 200 OK
X-Powered-By: Servlet/3.0
Content-Type: application/json
Content-Length: 24
Date: Thu, 03 Mar 2016 14:45:23 GMT

{"value":"ß_SomeLabel"}

{"value":"ß_SomeLabel"}

I have attached a service.xml, rewrite.xml, and a sample JAX-RS service for testing/troubleshooting purposes.
