Description:
Follow-up of: https://bugs.mysql.com/bug.php?id=77207
Page: https://dev.mysql.com/doc/refman/5.7/en/performance-schema-connection-attribute-tables.htm...

_runtime_version
_runtime_vendor

These are apparently sent by Connector/J

How to repeat:
See description

Suggested fix:
Document these so that other official and unofficial connectors can use the same attributes if applicable. This would also help for applications/frameworks to know which attributes are already taken by the connector.

re:  "Document these so that other official and unofficial connectors can use the same attributes if applicable. This would also help for applications/frameworks to know which attributes are already taken by the connector."

With respect to that last sentence, if the intent is for applications to know which connection attributes they can create themselves, *any* attribute name beginning with an underscore is reserved.

http://dev.mysql.com/doc/refman/5.7/en/performance-schema-connection-attribute-tables.html
says:

Attribute names that begin with _ are reserved for MySQL itself and should not be used by client applications. This permits new attributes to be introduced by MySQL without colliding with application attributes.
