Socket Appender has no default port value for UDP

[ppkarwasz]

The Socket Appender has default port values for TCP (4560) and SSL (6514), but has no default value for the UDP protocol.

I think we should add 4560 as default port also for UDP. What do you think?

Why? (I'm not against – I just want to know if it serves a particular use case.)

(Is either 4560 or 6514 registered port numbers for a particular service that supposedly accepts input from Log4j? If not, I think assigning defaults to those attributes was a mistake. One, we cannot revert due to backward compatibility concerns.)

Looks better in the docs. 😉

While I don't support many features (like the default values for TCP and SSL), I would prefer to have a configuration format with as few surprises as possible.

BTW: both those ports are unassigned by IANA. Maybe the idea was to write a Log4j Server that uses those ports.
