> Key: CXF-7802
> URL: https://issues.apache.org/jira/browse/CXF-7802
> Project: CXF
> Issue Type: Bug
> Components: JAX-RS
> Affects Versions: 3.2.5
> Environment: Mac OS X 10.13.6 (17G65)
> Tomcat 9.0.4

> h2. Problem
> When sending a request with a mapped query parameter name without value Apache CXF crashes with an IllegalArgumentException when the endpoint method gets invoked. This happens with primitive type endpoint method arguments mapped to a query parameter.
> h2. Example Code
>
> {code:java}
> @GET
> @Produces(MediaType.APPLICATION_JSON)
> @Path("/admin/roles")
> public Stream<Role> searchRoles(@QueryParam("search") String search, @QueryParam("page") @DefaultValue("1") int page, @QueryParam("limit") @DefaultValue("30") short limit) throws SqlException {
> ...do something...
> }
> {code}
>
> h2. Web Request
> Following request containing the query parameter without value triggers the exception
>
> {code:java}
> GET /admin/roles?page {code}
>
> h2. Exception
> {code:java}
> java.lang.IllegalArgumentException: null

> h2. Expected Behavior
> I'm not sure what the JAX-RS standard says but I would assume that the @DefaultValue annotation should be taken into account for such a scenario when a query parameter without value is passed in. At least the request router should not crash with an IllegalArgumentException and use the Java default value for primitive types instead of trying to assign null.
>
> My main problem is that @DefaultValue seems to be ignored when such a request is passed in. This is evident when the argument type is an object type such as String. Instead of using the declared default value the request router passes in null instead.
> The default value only appears to be evaluated if the query parameter name is undefined in the URI query parameters string.
