>Description:
The control flow of ServerSocket(int port, int backlog, InetAddress bindAddr) is as follows:

 this();
 impl.create(true);
 impl.bind(bindAddr, port);
 impl.listen(backlog);

The call to this() also calls impl.create(true), meaning that a second socket is created and the original socket is leaked. ServerSocket(int port) and ServerSocket(int port, int backlog) both call ServerSocket(int port, int backlog, InetAddress bindAddr) so they also leak a socket per call.
>How-To-Repeat:

>Fix:
Remove the call to impl.create() from ServerSocket(int port, int backlog, InetAddress bindAddr).
