1. Tracked by Slave::create_table(): class name don't exist for type: 246 #18. We discussing it offline with @darrenchinesedba.
2. Tracked by Met exception in get_remote_binlog cycle #19.
3. No binlog position is written. Looks as the effect of the errors above.

Since all mentioned problems have its own issues, I'll close this one.
