JDK-8293862 - javax/swing/JFileChooser/8046391/bug8046391.java failed with 'Cannot invoke "java.awt.Image.getWidth(java.awt.image.ImageObserver)" because "retVal" is null'
Description
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 with JDK-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:

According to the line numbers in the exception, this is the duplicate of JDK-8320692. In this case, at java.desktop/sun.awt.shell.Win32ShellFolder2$MultiResolutionIconImage.getResolutionVariant(Win32ShellFolder2.java:1459) at java.desktop/sun.awt.shell.Win32ShellFolder2$MultiResolutionIconImage.getBaseImage(Win32ShellFolder2.java:1438) whereas in JDK-8293862 the line numbers are different: at java.desktop/sun.awt.shell.Win32ShellFolder2$MultiResolutionIconImage.getResolutionVariant(Win32ShellFolder2.java:1440) at java.desktop/sun.awt.shell.Win32ShellFolder2$MultiResolutionIconImage.getBaseImage(Win32ShellFolder2.java:1419)

Likely it's a duplicate of JDK-8320692 because JDK-8293862 is already fixed in 21. Can you run the test case with assertions enabled? Pass -ea -esa options to the Java launcher.
