```
void connectionLost(java.lang.Throwable reason)
```
    This method is called after the connection's underlying socket has been closed. E.g., due to the Connection.close() request of the user, if the peer closed the connection, due to a fatal error during connect() (also if the socket cannot be established) or if a fatal error occured on an established connection.
    This is an experimental feature.
    You MUST NOT make any assumption about the thread that invokes this method.
    Please note: if the connection is not connected (e.g., there was no successful connect() call), then the invocation of Connection.close() will NOT trigger this method.
    
    Parameters:
    
    reason - Includes an indication why the socket was closed.
