Getting Exception with Java based uploader

We are using the the Java based ImageUploader in Version 1.1.101

We are getting reproduceable the following exception:

Exception class: class java.security.AccessControlException
-----
access denied (java.lang.RuntimePermission createClassLoader)
-----
java.security.AccessControlException: access denied (java.lang.RuntimePermission createClassLoader)
	at java.security.AccessControlContext.checkPermission(Unknown Source)
	at java.security.AccessController.checkPermission(Unknown Source)
	at java.lang.SecurityManager.checkPermission(Unknown Source)
	at java.lang.SecurityManager.checkCreateClassLoader(Unknown Source)
	at java.lang.ClassLoader.<init>(Unknown Source)
	at com.aurigma.imageuploader.upload.a.<init>(Unknown Source)
	at com.aurigma.imageuploader.upload.b.a(Unknown Source)
	at com.aurigma.imageuploader.upload.b.b(Unknown Source)
	at com.aurigma.imageuploader.upload.b.run(Unknown Source)
	at java.lang.Thread.run(Unknown Source)

It happens, when you Upload images (which seems to work the first time) and than upload images in the same browser session a second time.

I'm not sure, whether we are doing anything wrong, or whether the imageuploader is failing itself.

We have been migrating from an older Version of Image Uploader recently. The old version did not have this problem ! This is causing impressive customer support on our side, but we can not go back to the old version, because the old version is no longer signed !

Any help would be very much appreciated, because we have no more ideas, how to sort this problem out :(

Thanks,

p.s. This exception is thrown, if you have non images with the extension .jpg in one of your folders.

This is no real problem, as it does not seem to influenced the image uploader at all, just you get the exception inside your java log.

sun.awt.image.ImageFormatException: Unsupported JPEG process: SOF type 0xc3

thanks for your response.

We will try to prepare a basic example, where the error is reproduceable.

As you stated inside the other post, this problem will be added to your Bugtracking system. So, is there a estimate, when we can reckon a fix for this issue ?

Thanks again,
