在Java Swing应用程序中，有时会出现以下错误：
java.lang.IndexOutOfBoundsException: Invalid index
at javax.swing.DefaultRowSorter.convertRowIndexToModel(Unknown Source)
at sun.swing.FilePane$SortableListModel.getElementAt(Unknown Source)
at javax.swing.JList.getSelectedValue(Unknown Source)
当用户使用JFileChooser浏览目录时会发生这种情况。例外打印到输出consolle，但似乎它不会导致任何明显的问题。我无法重现此错误，但它发生在客户身上。机器。我可以忽略这个例外吗？它会导致其他一些隐藏的故障吗？
完整的堆栈跟踪如下。
Java版本是1.8.0_45。
