During the process of starting the JBoss server, if Database server is not available or not reachable, the server continuously pools for Database connection (does not even pool for number of attempts) and does not start the server.

and the stack is

10:41:12,876 WARN [JDBCExceptionReporter] SQL Error: 0, SQLState: null
10:41:12,876 ERROR [JDBCExceptionReporter] Cannot create PoolableConnectionFactory (Io exception: Unknown host specified )
