[OPENJPA-2943] Add the issue to the release notes
> MySQLDictionary.decorate() is out of date with MySQL Driver Changes
> -------------------------------------------------------------------
>
> Key: OPENJPA-2943
> URL: https://issues.apache.org/jira/browse/OPENJPA-2943
> Project: OpenJPA
> Issue Type: Bug
> Components: jdbc
> Reporter: Jody Grassel
> Priority: Major
>
> 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 read-replicas is no longer valid, and needs to be updated to support more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.
