How to Handle Exceptions Thrown by SwingWorker's Future?

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

SwingWorker does not expose any way to get an underlying exception. However, since SwingWorker provides a way to complete with a result using the done() method, you can rethrow the exception here, where it will be caught by the caller of the get() method on the Future.

// ...

@Override
protected void done() {
    if (str.equals("StartShedule")) {
        try {
            get();
        } catch (InterruptedException ie) {
            ie.printStackTrace();
        } catch (ExecutionException ee) {
            throw (ee).getCause();
        }
    }
}
