> System procedures are implemented as public static methods in org.apache.derby.catalog.SystemProcedures. These methods can be called by code in user-written procedures. This allows a user-written procedure to circumvent the SQL authorization checks which are supposed to limit some procedures to being called only by the DBO. I will attach a repro.
