>             Project: CXF
>          Issue Type: Bug
>          Components: JAX-RS
>    Affects Versions: 2.2.10
>            Reporter: Brad Cupit
>            Priority: Minor

> CXF sets a null collection, rather than an empty one, when the query param isn't in the
request
> Example:
>     @GET
>     @Path("/stuff")
>     public Response get(@QueryParam("option") Set<String> options) { ... }
> and http://localhost:8080/stuff is called (but ?option=abc is not on the query string),
then options will be null, but it should be an empty Set
> The javadocs in @DefaultValue says:
> If this annotation is not used and the corresponding metadata is not present in the request,
the value will be an empty collection for List, Set or SortedSet
> this seems similar to CXF-1675
