> MySQLDictionary.decorate() has a check to determine if the MySQL driver is of 
> type "com.mysql.jdbc.ReplicationDriver" (for utilizing read-only replica 
> nodes to relieve read-work on the primary database) – if it is, then it calls 
> conn.setReadOnly(true).  This is to ensure that, by default, reads are going 
> to the reader nodes, instead of the writer nodes.
> Later versions of the MySQL Connect J driver (as of v8) have done away with 
> the "com.mysql.jdbc.ReplicationDriver" class (see 
> [https://dev.mysql.com/doc/connector-j/en/connector-j-other-changes.html 
> section|https://dev.mysql.com/doc/connector-j/en/connector-j-other-changes.html,]).
> This means the current means of detecting whether the environment is using 
> read-replicas is no longer valid, and needs to be updated to support more 
> modern versions of Connect J.
