It is normal for the address to remain in use for a few minutes after
closing the Socket.
It is however extremely unusual to care which port number is chosen by
the client. If you don't specify a client port number, the system will
simply choose an available one.
If you really do need to specify the client port number, you can also
use setReuseAddress() and the address will become available again
immediately after you close the Socket.
