Description

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
org.apache.cxf.rs.security.jose.jwe.JweException: INVALID_COMPACT_JWE
    at org.apache.cxf.rs.security.jose.jwe.JweCompactConsumer.<init>(JweCompactConsumer.java:40)
    at org.apache.cxf.rs.security.jose.jaxrs.AbstractJweDecryptingFilter.decrypt(AbstractJweDecryptingFilter.java:44)
    at org.apache.cxf.rs.security.jose.jaxrs.JweClientResponseFilter.filter(JweClientResponseFilter.java:42)
...
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.
