Example code was unintentionally packed as nested zip archive. Fixed and updated reference.

> Can't instantiate a HttpClient within a spring loaded bean using RESTEasy.
> Depending on whether resteasy-jaxrs included in war archive (scope "compile") or not included (scope "provided"), the ModuleClassLoader is trapped by either a duplicate class object, or none at all.
> See http://community.jboss.org/message/640810 for further details and example code.
> Tried following workarounds, but failed:
> If you change the code not to instantiate HttpClient explicitly, as in
>   private ClientExecutor createClientExecutor()
>   {
>     ClientExecutor clientExecutor = new ApacheHttpClient4Executor();
>     return clientExecutor;
>   }
> the code runs fine. But then you can't attach Credentials (not acceptable). Or you need to query the ClientExecutor's HttpClient afterwards, and cast the result to DefautHttpClient -> Class loader issue is back again.
