                Instructions to Test:
                1. Open an elevated Command Prompt.
                2. Paste the following commands:
                cd /d C:\\
                mkdir FileChooserTest
                cd FileChooserTest
                mkdir target
                mklink /d link target

                3. Navigate to C:\\FileChooserTest in the JFileChooser.
                4. Use "Enable Multi-Selection" checkbox to enable/disable
                   MultiSelection Mode
                5. Single-selection:
                   Click "link" directory, the absolute path of the symbolic
                   link should be displayed. If it's null, click FAIL.
                   Click "target" directory, its absolute path should be
                   displayed.

                   Enable multiple selection by clicking the checkbox.
                   Multi-selection:
                   Click "link", press Ctrl and then click "target".
                   Both should be selected and their absolute paths should be
                   displayed.

                   If "link" can't be selected or if its absolute path is null,
                   click FAIL.

                   If "link" can be selected in both single- and multi-selection modes,
                   click PASS.
                6. When done with testing, paste the following commands to
                   remove the 'FileChooserTest' directory:
                cd \\
                rmdir /s /q C:\\FileChooserTest

                or use File Explorer to clean it up.
