Python中java访问桥的点击动作问题

问题描述

我设法使用 jab 从 java applet 中的某些控件获取描述或名称，并且单击操作成功运行。 java小程序需要一些时间来响应点击动作，点击动作后，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信息。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，我发现当我在下面的代码运行时手动单击该小程序上的某个按钮时，或者当点击操作发布并且小程序本身会做一些响应时，此时下面的代码将始终停止运行。

另外一点我发现，在python脚本运行过程中，applet中的任何状态变化都会导致python内核死亡。比如点击动作是post，小程序中会出现一些新的信息，然后python内核就死了。
