Description

Hi,

I'm currently working on the JSR-371 (MVC 1.0) TCK and ran into a weird issue when running it against TomEE 7.0.5 which include CXF 3.1.15.

For some reason @QueryParam doesn't work if I place it on a resource field. To be more concrete, in this code the query parameter isn't injected into the field:

@Path("inject-test")
public class InjectParamsController {

    @QueryParam("fieldValue")
    private String fieldValue;

    @GET
    public Response get() {
        // some resource code
    }

    public String getFieldValue() {
        return fieldValue;
    }

    public void setFieldValue(String fieldValue) {
        this.fieldValue = fieldValue;
    }
}

If I move the annotation to the getter, it is working as expected:

@Path("inject-test")
public class InjectParamsController {

    private String fieldValue;

    @GET
    public Response get() {
        // some resource code
    }

    @QueryParam("fieldValue")
    public String getFieldValue() {
        return fieldValue;
    }

    public void setFieldValue(String fieldValue) {
        this.fieldValue = fieldValue;
    }
}

Both ways work fine on Glassfish5 and Wildfly.

It would be great to get your thoughts on this. Something like "Yeah, this is a known bug" or perhaps "You are crazy, this MUST work, you are doing something wrong"
