Daniel John Debrunner commented on DERBY-2109:
----------------------------------------------

" We could always reload the policy file just before checking for a system 
privilege and then advise the user to grant derby.jar the above permission. "

Not sure that's a good idea, seems like the refresh policy should be an explict 
operation, not called on every security operation just because it might have 
changed. Such an approach could allow some form of denial of service attack 
because a failed attempt to do something still would call refresh, thus 
repeated calls to the disallowed operation would still have a potential effect 
on the VM. Possibly stalling it as the policy file is reparsed.

> Add mechanisms for controlling system-level privileges in Derby. See the 
> related email discussion at 
> http://article.gmane.org/gmane.comp.apache.db.derby.devel/33151.
> The 10.2 GRANT/REVOKE work was a big step forward in making Derby more  
> secure in a client/server configuration. I'd like to plug more client/server 
> security holes in 10.3. In particular, I'd like to focus on  authorization 
> issues which the ANSI spec doesn't address.
> Here are the important issues which came out of the email discussion.
> Missing privileges that are above the level of a single database:
> - Create Database
> - Shutdown all databases
> - Shutdown System
> Missing privileges specific to a particular database:
> - Shutdown that Database
> - Encrypt that database
> - Upgrade database
> - Create (in that Database) Java Plugins (currently  Functions/Procedures, 
> but someday Aggregates and VTIs)
> Note that 10.2 gave us GRANT/REVOKE control over the following  
> database-specific issues, via granting execute privilege to system  
> procedures:
> Jar Handling
> Backup Routines
> Admin Routines
> Import/Export
> Property Handling
> Check Table
> In addition, since 10.0, the privilege of connecting to a database has been 
> controlled by two properties (derby.database.fullAccessUsers and 
> derby.database.defaultConnectionMode) as described in the security section of 
> the Developer's Guide (see 
> http://db.apache.org/derby/docs/10.2/devguide/cdevcsecure865818.html).
