Example code doesn't compile on 1.8.13 about telnetspy HOT 2 CLOSED

So I decided to hack away at the problem and came up with this solution. It now compiles but I havn't tested it to see if it works. The compile errors go away:

After applying the above changes it is working fine for me. The author should update the code. Thank you!
