我设法从带有 jab 的 java 小程序中的某些控件中获取描述或名称，并且单击操作也成功运行。java小程序需要一些时间来响应点击动作，在点击动作之后，有时python脚本会继续运行剩余的行，但有时会崩溃并关闭而没有错误消息。在下面的代码中，我想将文本内容设置为文本框并单击按钮 5 次，不幸的是它总是在第一轮后崩溃。

在这里补充一点，我发现当我在运行下面的代码时手动单击该小程序上的某个按钮时，或者当单击操作发布并且小程序本身会执行一些响应时，此时下面的代码将始终停止运行。

还有一点我发现，在python脚本运行期间，applet中的任何状态变化都会导致python内核死机。比如点击动作是post，一些新的信息会出现在applet中，然后python内核就死掉了。
