STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
* Get an image, for example

    curl http://jruby.org/images/jruby-logo.png > jruby-logo.png

* Compile Main.java

public class Main {
    public static void main(String[] args) {
        try {
        Thread.sleep(3000);
        } catch (InterruptedException ie) {
        System.out.println("Interrupted!");
        }
        System.out.println("Hello World");
    }
}

* Start the program with the splash image

    java -splash:jruby-logo.png -XstartOnFirstThread Main



EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -

CUSTOMER SUBMITTED WORKAROUND :
There is no known workaround for this.  You can either display a splash image OR use the -XstartOnFirstThread option to enable Eclispe SWT or other libraries that require you to run on the main thread.
