When executing the following program on NetBeans 5.0 and also on NetBeans 5.5:

-------------------------------------------------------------------------------
public class MainClass 
{    
   public MainClass() 
   {
   }
    
   public static void main(String[] args)
   {
       try
       {
           System.out.print("Hello ");
           Thread.sleep(5000);
           System.out.print("world");
           Thread.sleep(5000);
           System.out.print("!");
           Thread.sleep(5000);
       }
       catch(InterruptedException e)
       {
           System.out.println(e);
       }
   }
}
-------------------------------------------------------------------------------

I get an initial pause of 15 seconds (the sum of the three Thread.sleep())
followed by the printing of the "Hello world!" text on the output window,
instead of the expected behaviour: each System.out.print() followed by a 5
seconds pause. Executing the program via command line and also via Eclipse, the
output is the expected one.
