Description:
according to the http://dev.mysql.com/doc/relnotes/mysql/5.7/en/news-5-7-13.html
Replication: Slaves running MySQL 5.7 could not connect to a MySQL 5.5 master due to an error retrieving the server_uuid, which is not part of MySQL 5.5. This was caused by changes in the method of retrieving the server_uuid. (Bug #22748612)
References: This issue is a regression of: Bug #21455603.
when the master version is 5.0.92, the slave version is 5.7.13, the update binlog had been replicated to the slave, but the slave error log shown like that:

How to repeat:
use the different mysql version for the replication
master:5.0.92
slave:5.7.13
