ADDITIONAL SYSTEM INFORMATION :
Observed at least on Microsoft Windows 7 64-bit, and Microsoft Windows 10 64-bit, always with build 1.8.0_191. The problem does not occur with 1.8.0_181 or 1.8.0_171.

A DESCRIPTION OF THE PROBLEM :
On Microsoft Windows systems with b191, when a SecurityManager is defined, opening a JFileChooser in a folder with broken shortcuts causes system popup messages to appear: "The item <somefile> that this shortcut refers to has been changed or moved, so this shortcut will no longer work properly.  Do you want to delete this shortcut?" 

The problem occurs in sun.awt.shell.Win32ShellFolderManager2.checkFile(File file, SecurityManager sm). In revision http://hg.openjdk.java.net/jdk8u/jdk8u/jdk/rev/12e8aa264316 code was added to check link targets, which ends up calling Win32ShellFolder2.getLinkLocation(true). The call to getLinkLocation with resolve=true causes the popup messages.


REGRESSION : Last worked in version 8u181

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Create a file on Windows desktop. Use Windows menus to create a shortcut to that file, also on Windows desktop. Delete the first file, leaving the shortcut.
Run a Java program, where a security manager has been defined with System.setSecurityManager, and create an instance of JFileChooser.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
No popup messages.
ACTUAL -
A system popup message appears: "The item <somefile> that this shortcut refers to has been changed or moved, so this shortcut will no longer work properly.  Do you want to delete this shortcut?"

        JFileChooser chooser = new JFileChooser();

        chooser.showDialog(null, "Open"); // not really needed
    }
}

CUSTOMER SUBMITTED WORKAROUND :
To circumvent the issue, define a security manager where checkRead throws SecurityException for broken shortcuts. In order to detect a broken shortcut, use a Win32ShellFolderManager32 to create an instance of Win32ShellFolder for the shortcut file, then invoke getLinkLocation(false) (via reflection as the method is not public) and confirm that the resulting target exists.
