How to print to the console in GWT

Question

I am debugging a GWT application and I need to print some stuff to the console for testing purposes. System.out.println and GWT.log don\'t work. Do

Yet another variation using the native console...

Add this class:

package XXX.XXX.XXX.XXX;

public class Debug {
    private static boolean isEnabled_ = false;
    public static void enable() { isEnabled_ = true; }
    public static void setEnabled( final boolean isEnabled ) 
    { isEnabled_ = isEnabled; }

    public static void log( final String s ) 
    { if( isEnabled_ ) nativeConsoleLog( s ); }

    private static native void nativeConsoleLog( String s ) 
    /*-{ console.log( s ); }-*/;
}

Then, enable debugging with it at some point, like upon starting the app:

public class XXXXXX implements EntryPoint {
    @Override
    public void onModuleLoad() {
        Debug.enable();
        ...
    }
}

Then just use it like so:

Debug.log("Hello World!");
