ADDITIONAL SYSTEM INFORMATION :
Mac OS Version 10.15.5
Have tested on versions of java from OpenJDK 11 to 14, and IBM J9 java running on mac and all have similar issue.

A DESCRIPTION OF THE PROBLEM :
It seems the latest OS Catalina version Version 10.15.5 (latest as of date June28 2020) return incorrect absolute path by JFileChooser.
I didn't recall this happening until the latest upgrade to Version 10.15.5

What happen is the directory select by JFileChooser will return a extra period directory.
eg Expected: /storage/hello/abc
Return /storage/hello/./abc instead. There is always a extra /./ reference. It should return absolute path without the irrelevant period. I think this is critical as some application may parse and consider extra period directory as error.





REGRESSION : Last worked in version 14.0.1

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the test code that return directory select by JFileChooser

For example selecting a directory
/storage/hello/abc


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
/storage/hello/abc
ACTUAL -
/storage/hello/./abc

---------- BEGIN SOURCE ----------


import javax.swing.*;
import java.io.File;

public class TestFileChooser {
  public static void main(String[] args) {

    final JFileChooser dirChooser = new JFileChooser();

    dirChooser.setCurrentDirectory(new java.io.File(".")); // Set initial directory
    dirChooser.setDialogTitle("Please select folder...");
    dirChooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY); // Select directories only not file !!!

    int returnVal = dirChooser.showOpenDialog(new JFrame());

    if (returnVal == JFileChooser.APPROVE_OPTION) {
      File file = dirChooser.getSelectedFile();

      System.out.println("selected: " + file.getAbsolutePath());
    }
  }
}
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
 Search and replace string "/./" with "/".
However this is not practical as apparently the api is not returning "correct" path.

FREQUENCY : always
