RESTEasy - Stacktrace in logs when throwing WebApplicationException - resteasy

Question

I am using Resteasy 2.3.3, bundled with JBoss-AS-7.1.3. I'm trying to
throw a new WebAppliationException, and the output (to the client) seems
fine, but I'm left with an unwanted stack trace in my log. I have a few
other Exceptions mapped, and I was wondering if the mapping was somehow
causing an issue ­ trying to wrap this Exception.
Simple example:
public class SimpleService {
#GET
#Path("stuff")
public String getStuff(final #QueryParam("param1") String param1,
#QueryParam("param2") String param2) throws ActionException {
if (param1==null && param2==null) {
throw new WebApplicationException();
}
I get the following exception:
[WARN] org.jboss.resteasy.core.SynchronousDispatcher#error - failed to execute: javax.ws.rs.WebApplicationException
Any ideas what this error might mean? How I could get rid of the messages?

I stumbled across another class in the javadoc - NoLogWebApplicationException, and it says:
WebApplicationExceptions are logged by RESTEasy. Use this exception
when you don't want your exception logged
