Sometimes when constructing and configuring a JFileChooser in our application, an InterruptedException is thrown. The problem is very intermittent (this typically occurs no more than 1/10 tries...sometimes we don't see it for long periods of time which leads us to believe a "fix" has worked, only to see it again later). The following code is being executed to construct and configure the JFileChooser:

        chooser = new JFileChooser( defaultLogDir );
        chooser.setFileSelectionMode( JSemiModalFileChooserC.FILES_ONLY );
        chooser.setMultiSelectionEnabled( true );
        chooser.setFileHidingEnabled( false );

Later, when the JFileChooser should be displayed, we execute the following code (in the swing thread):

        chooser.setAcceptAllFileFilterUsed( false );
        int returnValue = chooser.showOpenDialog( parentPanel );

The stracktrace from the exception is:

java.lang.InterruptedException
            at javax.swing.filechooser.FileSystemView.getFiles(FileSystemView.java:401)
            at javax.swing.plaf.basic.BasicDirectoryModel$LoadFilesThread.run(BasicDirectoryModel.java:194)
    java.lang.InterruptedException
            at sun.awt.shell.ShellFolderManager.createShellFolder(ShellFolderManager.java:26)
            at sun.awt.shell.ShellFolder.getShellFolder(ShellFolder.java:236)
            at javax.swing.filechooser.FileSystemView.getShellFolder(FileSystemView.java:486)
            at javax.swing.filechooser.FileSystemView.getFiles(FileSystemView.java:409)
            at javax.swing.plaf.basic.BasicDirectoryModel$LoadFilesThread.run(BasicDirectoryModel.java:194)

My hunch is that this is probably a threading issue. Could this be caused by the fact that the JFileChooser constructor was not called in the swing thread?

This problem is consistently reproducible at the customer end , but not at our end.
Hi Kannan

Here is the exact cut/paste from customer's system

Fix is required for 1.5.0_xx
