ADDITIONAL SYSTEM INFORMATION :
Windows 10, Windows 10 pro, Windows 11
A DESCRIPTION OF THE PROBLEM :
Opening Windows folder with JFileChooser and com.sun.java.swing.plaf.windows.WindowsLookAndFeel causes a NullPointerException: Caused by: java.lang.NullPointerException: Cannot invoke "java.awt.Image.getWidth(java.awt.image.ImageObserver)" because "retVal" is null
Probably somehow related withJDK-8293862, JDK-8320692.
Problem does not occur with JDK 23.0.0.beta.11. so a backport might help.
Problem was also reported by customers who used a network share to open files. But I was not able to reproduce that- definetely reproducible by opening the windows folder
REGRESSION : Last worked in version 17.0.10
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Use windows Operating System (windows 10 or 11).
Set Look and feel to "com.sun.java.swing.plaf.windows.WindowsLookAndFeel"
Create a Swing dialog that opens a JFileChooser.
Navigate to Windows Folder.
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Windows directory opens and all entries are shown
ACTUAL -
Windows folder is not opened, JFileChooser can not open any other directory afterwards. NPE is thrown:
Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException: Cannot invoke "java.awt.Image.getWidth(java.awt.image.ImageObserver)" because "retVal" is null
