无法从 Future< 获取 ArrayIndexOutOfBoundsException，如果线程启动 Executor，>和 SwingWorker

我通过使用Executor为SwingWorker玩多线程，并且我在那里错误地从Vector中识别出错误的元素，看起来就像这个代码一样，忽略了Vector中的元素不存在

我的问题 - >如何/有可能以某种方式捕获此异常

简单输出

run:
Thread Status with Name :StartShedule, SwingWorker Status is STARTED
Thread Status with Name :StartShedule, SwingWorker Status is DONE
Thread Status with Name :StartShedule, SwingWorker Status is STARTED
Thread Status with Name :StartShedule, SwingWorker Status is DONE
Thread Status with Name :StartShedule, SwingWorker Status is STARTED
Thread Status with Name :StartShedule, SwingWorker Status is DONE
BUILD SUCCESSFUL (total time: 11 seconds)

通过取消注释

//changeTableValues1(); // un-comment for get ArrayIndexOutOfBoundsException

一切都是正确的，我得到 ArrayIndexOutOfBoundsException 和输出是

编辑：

在 done（） 方法中添加了从 Future#get（） 重新抛出的（通过@takteek个很好的建议）

@Override
    protected void done() {
        if (str.equals("StartShedule")) {
            try {
                get();
                //errLabel.setText(String.valueOf(get()));
            } catch (InterruptedException ie) {
                ie.printStackTrace();
            } catch (ExecutionException ee) {
                ee.printStackTrace();
            }catch (IllegalStateException is) {
                is.printStackTrace();
            }
        }
    }

但是输出仍然是并且只有，很难从这个黑匣子中获得任何异常Got exception
