Add GRANT/REVOKE mechanisms to control which jar files can be mined for user-created objects such as Functions and Procedures. In the future this may include Aggregates and Function Tables also. The issues are summarized on the following wiki page: http://wiki.apache.org/db-derby/JavaRoutineSecurity. Plugin management can be tracked by this JIRA rather than by DERBY-2109. This is a master JIRA to which subtasks can be linked.
