FULL PRODUCT VERSION :

Java(TM) SE Runtime Environment (build 1.6.0_22-b04)
Java HotSpot(TM) Server VM (build 17.1-b03, mixed mode)

ADDITIONAL OS VERSION INFORMATION :

Kernel release: 2.6.16.60-0.37_f594963d-smp

EXTRA RELEVANT SYSTEM CONFIGURATION :
KDE 3.5.1

A DESCRIPTION OF THE PROBLEM :
With Java version 1.6.0_22, the splash image indicated in the command line is showed partially. The top or the bottom of the image is chopped / cut / truncated.

But if you load the splash from Java code, without specifying it in the command line, using the method setImageURL from SplashScreen class, the image is showed correctly.

With Java version 1.6.0_10 it works correctly.
Command line example:
> java -splash:$HOME/images/splash.gif SplashTest

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Taking the following example code.
Changing "path to image" for a path to a rectangular image for using as splash, you should reproduce the bug.

excute the comand line
> java -splash:/path to image/splash.gif SplashTest



EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The image is totally and correctly visualised.
ACTUAL -
First, you will see the splash chopped / cut / truncated during 3 seconds.
Afterwards, the image is reloaded by the main code and the splash is visualised totally for 3 seconds more and the application finish.

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
(change "path to image" for an existent path)
====================================
import java.awt.*;
import java.net.URL;

public class SplashTest {
   
public static void main(String args[]) throws Exception {
   System.out.println("Splash test");
   SplashScreen splash = SplashScreen.getSplashScreen();
   Rectangle rec = splash.getBounds();
   Dimension dim = splash.getSize();
   System.out.println("Rectangle: "+ rec);
   System.out.println("Dimension: "+ dim);
   Thread.sleep(3000);
   splash.setImageURL(new URL("file:///path to image/splash.gif"));
   Thread.sleep(3000);
   System.out.println("Test finished");
}

}
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Excuting in the main the code

SplashScreen splash = SplashScreen.getSplashScreen();
splash.setImageURL(new URL("file:///path to image/splash.gif"));
