The test fails for JFileChooser selection mode set to `DIRECTORIES_ONLY`. For `DIRECTORIES_ONLY `mode, there may not be any directories in home directory and due to that test failed. Added the code to create temporary directories and files for the test. Tested the current change on the machine it failed for multiple times, no failure observed. CI link attached in JBS.
