Json.Object not handling strings correctly in GWT

[GoogleCodeExporter]

When building a Json.Object by putting in values, this results in "null" values 
for all string types on the GWT platform for me:

        Json.Object data = json().createObject();
        data.put("name", "string");
        data.put("other", "string");
        data.put("number", 1234);
        Json.Writer writer = json().newWriter();
        writer.object(data);
        log().info("Sending: "+writer.write());
        // Sending: {"name":null,"other":null,"number":1234}

I am using trunk, but I also think that it worked somewhen before. Not 100% 
sure what's wrong there.

Interesting. If I do this, BOTH work:

        Json.Object data = json().createObject();
        data.put("name", "string");
        data.put("other", "string");
        data.put("number", 1234);
        Json.Writer writer = json().newWriter();
        writer.object(data);
        log().info("Sending: "+writer.write());
        Map<String,Object> data2 = new HashMap<String,Object>();
        data2.put("string", "string");
        data2.put("number", 1234);
        writer = json().newWriter();
        writer.object(data2);
        log().info("Sending2: "+writer.write());
