18  * <P>This is a specialized RMI Security Manager for RmiJdbc when _embedded_
19  * applications/components are being accessed through RmiJdbc driver and
20  * run in the same JVM than RmiJdbc.
21  * This is required in order for the RMI threads to perform successfully
22  * when accessing database/local files for instance and performing I/O
23  * operations. The default RMI Security Manager is very restrictive and does
24  * not allow RMI thread to perform some of the I/O operations for instance.
25  *
26  * <P><B>Note:</B> There might be a cleaner solution in a near future, but
27  * right now this one allows embedded applications that does I/O operations
28  * throughout the RMI thread(s) to run inside RmiJdbc server.
