             Summary: HttpServletRequest injection via Context in setter
                 Key: CXF-6190
                 URL: https://issues.apache.org/jira/browse/CXF-6190
             Project: CXF
          Issue Type: Bug
          Components: JAX-RS
    Affects Versions: 3.0.3
            Reporter: Zdeněk Obst


I'm trying to inject HttpServletRequest to my JAX-RS resource via @Context 
annotation. It works fine if I inject it via method parameter. But I don't want 
to "mess" my interfaces with that so I'd like to inject it via setter.

I use this simple method (I'm using Kotlin but I the issue should be the same 
for Java):

    var req : HttpServletRequest? = null

    Context
    fun setRequest(req : HttpServletRequest) {
        this.req = req
    }

The thing is, that the setter is called via reflection in 
org.apache.cxf.jaxrs.utils.InjectionUtils in method injectThroughMethod. The 
method name is correct but as parameter value is instance of 
ThreadLocalHttpServletRequest which clearly is not HttpServletRequest (it is 
not inherited class) so this gets thrown: 

java.lang.IllegalArgumentException: object is not an instance of declaring class
