//!
//! This test is also an example of reconnection of the client in a multi-threaded process.
//!
//! This test:
//!
//!   1. Create threaded client without connection.
//!   2. Fetch specific JMX attribute (expect to fail).
//!   3. Connect to server.
//!   4. Fetch an attribute from the server.
//!   5. Disconnect from the server.
//!   6. Fetch specific JMX attribute (expect to fail).
