Exception when adding jar/folder to library

When I click on the button to add the jar files in the library that I just created, the window to choose the files does not open, only an exception is shown in the netbeans status bar.

Reproduce the failure through Tools > Library > New Library > Add Jar/Folder on Windows 10 with Apache NetBeans 16, then inspect the linked messages.log for the comparison exception. Trace the library file-selection entry point and verify that adding a JAR or folder opens the chooser without the exception.
