We have been running Vibe 3.0 for a couple years with no issues but suddenly users have begun to get java errors when trying to edit a file from Vibe. When a file entry is opened and the "Edit this file" link is clicked, a dialog pops up that says :

Error from command:
java.security.AccessControlException: access denied (java.io.FilePermission <<ALL FILES>> execute)

Has anyone else seen this? Could it be related to some windows security update perhaps? Any ideas how to resolve would be appreciated. This happens with regular users as well as admin.

Vibe is running on SLES 10 with mysql. We are using IIS Windows Authentication.
