I get the following exception once a timer has finished execution. It's not
hindering what I do but wanted to know is this something due to my timer.
Thanks.
JPDL Excerpt:
System.out.println("In state wait!!!");
System.out.println("Did the timer fire???");
System.out.println("Leaving wait state!!!");
