           Summary: JSObject is not valid on Javascript side
          Severity: normal
    Classification: Unclassified
                OS: Linux
          Reporter: helpcrypto at gmail.com
          Hardware: x86
            Status: NEW
           Version: unspecified
         Component: Plugin
           Product: IcedTea-Web

I have detected an error (not a crash) when using JSObject, that differs from
'official' oracle jre behaviour.

Consider the following code:
    public class MyApplet extends Applet {
        public static Applet applet = null;
        @Override
        public void init() {
            applet = this;
        }
        public JSObject testFunction() {
            return AccessController.doPrivileged(new
PrivilegedAction<JSObject>() {
                @Override
                public JSObject run() {
                    JSObject win = JSObject.getWindow(applet);
                    JSObject js = (JSObject) win.eval("new Object();");
                    //...
                    js.setMember("code", 0);
                    return js;
                    }
                });
            }
        }
    }

On javascript side, invoking this way:
    var obj=applet.testFunction();
    alert(obj.code);


This doesn't work, and says undefined. obj is [object] (but not a valid js
object) and I cant enumerate properties using:
    var txt='';
    for(var a in cert){
        txt+='obj['+a+']='+obj[a]+'\n';
    }
    alert(txt);

The same code works on Oracle and obj.code==0 :)

According to http://icedtea.classpath.org/wiki/IcedTea-Web, as Im using
netscape.javascript.JSObject, I should add plugin.jar to my classpath when
building, but it should work/run properly on pages. Should i do anything else?

Maybe related to http://icedtea.classpath.org/bugzilla/show_bug.cgi?id=347 ?

Thanks a lot for your help!
