How can I map semicolon-separated PathParams in Jersey?

Is there a way to use this parameter style:

/products/123;456;789

in JAX-RS with Jersey? If I use PathParam, only the first parameter in the list is returned. I tried to escape the semicolon but then Jersey returns only "123;456;789" as the value of the first parameter list entry

I declared the GET method as

public List<Product> getClichedMessage(@PathParam("ids") List<String> idList)

Update: I am referring to the Jersey user guide for Jersey 1.1.5:

In general the Java type of the method parameter may (...) 4) be List, Set or SortedSet, where T satisfies 2 or 3 above. The resulting collection is read-only. (...) Sometimes parameters may contain more than one value for the same name. If this is the case then types in 4) may be used to obtain all values.

Update: here is my test code:

package de.betabeans.resources;

import java.util.List;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;

@Path("/test")
public class TestResource {

    @GET
    @Path("/{ids}")
    @Produces({"text/plain"})
    public String getClichedMessage(@PathParam("ids") List<String> idList) {
        return "size=" + idList.size();
    }

}

Test URL with semicolon escaped: http://localhost:8080/resources/test/1%3B2%3B3

Update: the changelog for Jersey 1.3 include this information:
