所以我遇到了这种晦涩难懂的错误，我不知道这意味着什么。在不查看我的代码的情况下，有人可以告诉我导致此错误的原因以及此错误的可能解决方案吗？任何帮助将不胜感激。

这是错误：

在没有看到任何代码或任何说明问题的SSCCE的情况下，我们基本上只能猜测发生了什么。我敢打赌，您在弄乱另一个 Swing 组件Thread，这ArrayIndexOutOfBoundsException是在错误线程上删除组件的结果。

为了调试它，我将首先使用CheckThreadViolationRepaintManager并修复它指示的任何错误。如果这不起作用，我会尝试为 设置一个断点ArrayIndexOutOfBoundsException，查看哪个容器导致错误，并尝试在其上为任何添加和删除方法设置断点，以确定谁删除了导致异常的组件（可能在错误的线程上，您可以使用该方法轻松检查EventQueue.isDispatchThread()）
