Can’t get ArrayIndexOutOfBoundsException from Future and SwingWorker if thread starts Executor

I’m not sure it adds much, but I got the expected Caused by using the variation of takteek’s answer shown below. I ran it from the command line to be sure the IDE wasn’t “helping”.

$ java -cp build/classes TableWithExecutor
