Description:
If innodb_additional_mem_pool_size is added to the Options File for a recent MySQL version, MySQL fails to start with a related error.

How to repeat:
Install MySQL 5.7.21, connect with MySQL Workbench 6.3.10, navigate to Management, Instance, Options File, InnoDB tab, Memory section. Check innodb_additional_mem_pool_size and enter a value like '32M'. Apply change, restart MySQL. MySQL fails to start with an error in the log:
[ERROR] unknown variable 'innodb_additional_mem_pool_size=32M'

Suggested fix:
It would be helpful if this option was removed from the Options File interface when MySQL workbench detects a MySQL version that does not support this option. According to the MySQL documentation, this option was removed in 5.7.4.

Thank you for the bug report. Please attach (use Files tab for) a screenshot of innodb_additional_mem_pool_size in InnoDB->memory section, I couldn't find in Windows 10 Pro. Thanks in advance.

Thanks for the quick response. I can no longer find that option in the interface either. Not sure what changed, but I'll close this issue and not trouble you further unless I can recreate it at a later time.
