Yes, it is an optional extension and I do provide it. I have a few thousand mac customers and this is the only one to ever report this issue so the issue is something to do with their configuration, possibly installtion of some other software but Im not very au fait with tyhe internals of how java is configured on a Mac 

More likely it's a straightforward classpath issue.

How is your app deployed to a user's machine? As an app-bundle, a double-clickable jar, a JNLP app, or something else? Is there a URL where we could download it and find out for ourselves?

Do you have a Mac to test things on? I can give you procedures to probe the possible classpath issues, but they use non-Java Mac apps running on a Mac.

My app is deployed as an app-bundle and can be downloaded from http://www.macupdate.com/info.php/id/18360, and yes I have a mac to test myself.
My suspicion is that somewhere in the pathname leading to your installed app on this customer's machine, there is a directory name that contains a "!" or a ":". The ":" would appear in the Finder as a folder-name with a "/" embedded in it. For example, "A/V" is a common abbreviation for audio/video apps that will be problematic for a Java-based a/v app.
Ok I tried this I created a Folder called Test:Folder and a folder called Test\!Folder in a Terminal Window, these displayed as Test:Folder and Test\Folder in Finder. Putting my application in either of these folders failed from working BUT it didnt fail with the same error as the customer was getting.
To get the Unix pathname of a folder or file, open a new untitled document in TextEdit.app. If it's Rich Text, choose "Make Plain Text" from the Format menu. The next step won't work in a Rich Text document, only a Plain Text one.

Next, go to the Finder and navigate to where your app is installed. Drag the app's icon onto the blank text area of the plain text untitled document and drop it. The pathname should appear.

Finally, inspect the pathname for ":" or "!", or have the customer copy and paste it in an email to you.

You should try this yourself, FWIW. That is, put your app in a folder with a "!" in it and try to run it. Same for a folder with a Finder-name that has a "/" in it. Also try the TextEdit.app procedure and see how it works when your app is in one of these folders.
I have asked the customer to do this for me, but because the error they get is different to the error I get I'm not very confident this will be the cause.

thanks Paul
