Resolution

The permissions change is per product design. In speaking with Engineering, when modifying a Management Module (that is when you create/modify/remove an element), we delete the existing MM jar file, then create a new MM jar file and save it with the minimum default permissions for the user that starts the Enterprise Manager. For example, if I create a user ABC and it owns the EM executable, when they start the EM and the MM is modified, then the new MM jar file will have the user's default minimum permissions.

So that is why you see  a change from 775 to 640.
