Description:
http://dev.mysql.com/doc/internals/en/text-protocol.html#com-process-info indicates that COM_PROCESS_INFO has been deprecated since MySQL 4.1.  However, it still functions:

mysql> SELECT event_name, count_star, sum_errors
    -> FROM events_statements_summary_global_by_event_name
    -> WHERE event_name LIKE 'statement/com/Processlist';
+---------------------------+------------+------------+
| event_name                | count_star | sum_errors |
+---------------------------+------------+------------+
| statement/com/Processlist |         16 |          0 |
+---------------------------+------------+------------+
1 row in set (0.02 sec)

How to repeat:
Send COM_PROCESS_INFO (0x0a) to server.

Suggested fix:
Remove support for COM_PROCESS_INFO in MySQL 5.7.
