事件分派期间发生异常：java.lang.ArrayIndexOutOfBoundsException：0＆gt; = 0

Question

有时会遇到此异常。我真的不知道哪里有问题，如果我在下面的代码中使用线程我得到错误，否则没有。如果我连续点击则会出现问题 事件调度期间发生异常：

 private Thread progress_thread;
boolean threadStatus;

private void useThread(final String opt) {
    try {

        Runnable runnable = new Runnable() {

            public void run() {
                if (opt != null && opt.equalsIgnoreCase("searchbyMid")) {                       
                    callGlasspane();
                      constructDynamic();
                    closeGlasspane();
                }else if(opt != null && opt.equalsIgnoreCase("searchbyQrybased")){
                    callGlasspane();
                      createGUI();
