Question

因此,我忘记了这种模糊错误,我不知道它意味着什么。如果不看我的法典,有人会告诉我,造成这一错误的原因是什么? 任何帮助都将受到高度赞赏。

这里的错误是:

Answer 1

if you are using swing use worker threads to control the components worker thread tutorial

Answer 2

没有看到任何法典或SSCCE,这表明我们基本上只能猜测正在发生的问题。请您在另一个<条码>、<>条码/代码>和<条码>上与您的互换部分接洽。 ArrayIndexOutOfBoundsException是拆除错误线上部件的结果。

In order to debug this, I would start by using the CheckThreadViolationRepaintManager and fix any errors it indicates. If this does not work, I would try putting a breakpoint for the ArrayIndexOutOfBoundsException, see which container causes the error and try to put breakpoints for any add and remove method on it to determine who removes the component causing the exception (probably on the wrong thread, which you can easily check with the EventQueue.isDispatchThread() method )
