This is supported by many TLS implementations and also by several parsers such as Wireshark. Supporting this will greatly ease in debugging TLS problems.

Someone also may want to introduce log format for MSS or XSS as well. Instead, please consider to make use of the features of Java Logger if you want to write the log to files, or use any special format.

@XueleiFan I'd really like to move this forward but I'm uncertain what changes you want me to make. This extra debugging information will be very valuable to those of us debugging Java TLS connections.
