JAX-RS @PathParam Cannot resolve symbol for parameter with a regex

If a @Path has a regex in it, IntelliJ is marking them as being unresolved in the @PathParam's

Minimal example which does compile fine:

package com.whatever
import javax.ws.rs.*;

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

    @GET
    @Path("/{param1}")
    public void getGood(
            @PathParam("param1") String param1
    ) {

    }

    @GET
    @Path("/{param1:.+}")
    public void getBad(
            @PathParam("param1") String param1
    ) {

    }

}
