我的应用程序有问题，有时会在控制台中返回此错误，但我找不到来源(所有来源未知)。出现此错误后应用程序似乎可以正常工作，但我想了解发生了什么...我该怎么做？
谢谢你，对不起我的英语!

最佳答案
查看 BasicListUI.updateLayoutState() 的源代码，只有当显示的列表在方法执行期间更改大小时才会发生这种情况。
最可能的原因是您正在从 event dispatch thread 之外修改模型.这是一个严重的问题，因为它可能导致各种奇怪的行为甚至损坏数据。
要解决这些问题，请使用 SwingUtilities.invokeLater()每当您需要从 EDT 外部操作模型时。
