Subject [jira] Created: (DERBY-467) Restrict direct access to priviliged blocks from application code

Restrict direct access to priviliged blocks from application code

         Key: DERBY-467
         URL: http://issues.apache.org/jira/browse/DERBY-467
     Project: Derby
        Type: Bug
  Components: Security  
    Reporter: Daniel John Debrunner
 Assigned to: Daniel John Debrunner 

In looking at the privilged blocks in Derby  several are accessible from application code,
either as in public/protected methods and public classes. The fix for this includes:

- making packages in the jar files sealed wherever possible
- making classes and methods with privilged blocks  as private as possible (private or package
for methods, package for classes)

As Derby moves towards a more client server approach (e.g. see grant/revoke) I started to
perform a security analysis of the priviliged blocks, but realised it would be easier if I
fixed the obvious problems first.
