FULL PRODUCT VERSION :
Everything is fine until JRE 1.6.0.21 (included) and the issue is reproduced with all later versions (all tested) including the lastest one 1.6.0.25

ADDITIONAL OS VERSION INFORMATION :
Windows XP SP3 FR with most all updates

A DESCRIPTION OF THE PROBLEM :
In the application "Serena Collage" used in our company, the following error message appears when a user click on a button which should open a new screen (containing text and images) :

java.security.AccessControlException: access denied (java.net.SocketPermission 10.19.160.93:80 connect,resolve)

Here is the Java log when the user click on the button until the error appears :

The issue seems close to the following one found in your database (http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7027935) except that, on our case :
- The images are on the same host.
- The issue doesn't happens to ALL the users of the machines used. Indeed, on the same machine, some users are ok while others have it (usualy, my Admin account is the one more likely to have the issue... but I've tested with the accounts of other admins and they are ok so not sure it's linked to the fact I'm Admin).
- The issue doesn't happens on ALL machines. We haven't found the specificity of the ones on which it happens. Even after having installed all the same Microsoft Updates on the machines, some are ok while others aren't.
- The issue didn't start on 1.6.0.16 but clearly on 1.6.0.22 (the current solution to the issue is to downgrade the machines to 1.6.0.21 which garanties everything works perfectly).

There is a very interesting fact : We tried to investigate the issue with Fiddler 2 ... but when it works it's impossible to reproduce the issue on the machines which usually have it. And as soon as you turn off Fiddler, the issue appears again on those machines.
But we don't know why that is...

REGRESSION. Last worked in version 6
