>             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):
> {code:java}
>     var req : HttpServletRequest? = null
>     Context
>     fun setRequest(req : HttpServletRequest) {
>         this.req = req
>     }
> {code}
> 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
