There is a bug in awt_FileDialog.cpp in that it never calls load_shell_procs().

If setFilenameFilter() is called with a non-null object, then:

    ofn.Flags |= OFN_ENABLEINCLUDENOTIFY;

is executed. On Win2000 and Win98 (maybe Win98SE or with some upgrade, Comdlg32.ocx Version 6.00.8169) this will cause CDN_INCLUDEITEM notifications to occur. Handling for this notification calls:

    get_path_from_idlist(pidl,szPath)

However, nowhere in awt_FileDialog.cpp is load_shell_procs() called to insure the get_path_from_idlist function pointer is set. Calling this function with the pointer still set to null crashes the VM.

With a sufficiently up to date version of Windows 98 or Windows 2000, the following program should crash:


import java.io.*;
import java.awt.*;
public class FileDialogBug
{
static void main(String[] args)
{
FileDialog fDlg = new FileDialog(new Frame());
fDlg.addNotify();
fDlg.setFilenameFilter(new MyFilter());
fDlg.show();
System.exit(0);
}
}

class MyFilter implements FilenameFilter
{
public boolean accept(File dir,String name) { return true; }
}
