URI Not Absolute

[kehn]

I'm getting the following stacktrace:

errors.GrailsExceptionResolver IllegalArgumentException occurred when processing request: [GET] /app/recommend
URI is not absolute. Stacktrace follows:
java.lang.IllegalArgumentException: URI is not absolute
    at java.net.URI.toURL(URI.java:1080)
    at grails.plugins.rest.client.RestBuilder.doRequestInternal(RestBuilder.groovy:93)
    at grails.plugins.rest.client.RestBuilder.get(RestBuilder.groovy:53)

    at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908)
    at java.lang.Thread.run(Thread.java:680)

Using this code (snippet):

def resp = new RestBuilder();
def r = resp.get("http://grails.org/api/v1.0/plugin/acegi/");
resp.json instanceof JSONObject;
resp.json.name = "acegi";

This error does not happen if I remove the JSON lines and instead I get a plain text response back.

I've tested above code, it's still worked with Grails 2.2.1

I have this problem in grails 2.2.3

I have this same problem in grails 2.4.2

def index(Integer max) {
        (new RestBuilder()).rest.get("http://localhost:8080/eca-proto-server/api/animal") {
            acceptType  MediaType.APPLICATION_JSON
        }
    }
