JweClientResponseFilter fails to decrypt response, when it has status 204 No Content
For my current project I am trying to get familiar with the cxf JOSE framework. Currently I am running into a problem with JWE trying to encrypt request and response with compact serialization. I have a GET request where the response is correctly encrypted and decrypted, and I have a POST request where the response sends status code 204 and the body is obviously empty.
The response fails with a warning "WARNUNG: 5 JWE parts are expected" and an exception
Test case and test log with exception are attached.
I debugged the code a bit and it seems to me the filter method in JweClientResponseFilter fails to identify the body is empty and therefor calls the decrypt method, which it shouldn't
I ran the test case using 3.2.4 and 3.3.0, but also other versions will be affected.
