JFileChooser Win32ShellFolder2 pid

Hello,

I'm frequently experiencing a jvm crash two different winXP machines.

This happens when I open a JFileChooser instrumented with a FileSystemView.

The problem is both on jdk1.5.0_10 and on the new jdk1.6.0 final.

Googling around it seems that this is a quite common problem of the jdk on windows.

Here's an extract of the PID logs I get:

Your error seems very similar to mine, http://forum.java.sun.com/thread.jspa?threadID=5118746&messageID=9411204#9411204

It抯 a very weird error. But I think I抳e sorted it. I抣l talk you through, shall I?

Ok, first I defined a single global JFileChooser like this:

// The open file chooser

private JFileChooser chooser = new JFileChooser();

Before, I had a local one for each method that uses the file chooser.

Then at the end of the method were the chooser is use, take my open() for example, I reset all the values that had changed. I抣l show you what I mean.

public void open() throws

FileNotFoundException,IOException,ClassNotFoundException

{

// Can't choose all

chooser.setAcceptAllFileFilterUsed(false);

// Set mutable selection

chooser.setMultiSelectionEnabled(true);

// Add the file fiter

chooser.addChoosableFileFilter(new Track.TrackFilter());

// Add the track list filter

chooser.addChoosableFileFilter(new TrackListFilter());

// If the show result it accept

if (chooser.showOpenDialog(null)==JFileChooser.APPROVE_OPTION)

{

// . . .

}

// Reset for next time around

chooser.setSelectedFile(null);

chooser.setCurrentDirectory(null);

chooser.resetChoosableFileFilters();

}

Note at the top of the method, I have added a couple file filters, and at the bottom, I reset them. I also reset the selected file and current directory.

The current directory and selected file are changed in the showOpenDialog() and so must be reset.

I don抰 know you have to reset them, but it seems you have to.

Also note, if you are using a FileView, you properly have to reset that to null at the bottom as well. The same might apply to any other attribute you change.

Please try out these ideas and see if they work for you.

Thanks Luke,

sadly your mods can't be applied to my case, as

1) the crash happens just before the JFileChooser shows.

2) I create a new "fresh" JFileChooser each time.

I've searched in the bug database and it seems there's a lot of work and fixes to do for the JFC-Swing folks around the JFileChooser, still on JDK6.0.

The problem is that I'll have to explain my customers to be careful when selecting a file from disk as it may crash the application.. :-(

I don't want to flame here, but there's a MAJOR problem with the JfileChooser on windows and I would like to get it fixed asap..

Cheers,

Mik

Has anyone else been seeing this or figured out a way to stop it from happening? I've been experiencing the same problem throughout my application everywhere that I create JFileChooser objects. I pretty much have the exact same crash report as the other two posters here. I've also noticed that it happens on the second or third time I open a JFileChooser object. I've tried to create a simple test case that will reproduce the problem but haven't been able to. Any insight would be greatly appreciated.
