Hvad går der galt her??

Hvorfor har jeg fornemmelsen, at JEDPlus leger 100 meter fejlmeddelelse på tid med mig?

Programmet ser sådan ud:
**********************************************************************************************************************
/*This Is a Test
*/
class Test
{
static void main(String[] args)
{
System.out.println("This Is a Test");
}
}
**********************************************************************************************************************
Og det her er svaret hver gang når jeg Compiler, ("gælder for alle programmer"):
**********************************************************************************************************************
