Jan Engehausen commented on CXF-5508:
-------------------------------------

Hello Sergey, sorry for responding so slowly. I have to check our code at work once more, at the moment it appears that our initial interpretation is wrong. http://docs.oracle.com/javaee/6/api/javax/ws/rs/core/Request.html#evaluatePreconditions%28javax.ws.rs.core.EntityTag%29 says that it returns non-null if the preconditions are not met. In our case we send a If-None-Match with the previously obtained ETag value and an If-Modified-Since with the previously obtained modification date. Reading your response and the JavaDoc I'd say the current behaviour is correct. But please let me check this with the our implementation - I'll update the issue once more tomorrow. 

Thank you for looking into this!

> The problem I reported in https://issues.apache.org/jira/browse/CXF-4231 is back since 2.7.6; we noticed when upgrading to 2.7.8. See also https://fisheye6.atlassian.com/browse/cxf/branches/2.7.x-fixes/rt/frontend/jaxrs/src/main/java/org/apache/cxf/jaxrs/impl/RequestImpl.java?r2=1503661&r=1494596
> The concrete change/problematic part: if (rb != null) { => if (rb == null) {
> Any chance for a fix in the next release?
