             Summary: Invalid URL encoding causes error 500
                 Key: CXF-7015
                 URL: https://issues.apache.org/jira/browse/CXF-7015
             Project: CXF
          Issue Type: Bug
          Components: JAX-RS
    Affects Versions: 3.0.4
            Reporter: Sanjay Patel


When using Apache CXF JAX RS Client 3.0.3
We would get a 400 Response with URLDecoder: Incomplete trailing escape (%) pattern.

Using Apache CXF JAX RS Client 3.0.4 and above we see the below issue.

If we make a request using JAX RS to Spring with an invalid URL encoding, such as %3, we are getting a 500 Response, and an BufferUnderflowException. As seen below.
