Subject:MySQL Connector/Java 8.0.9-rc has been released
View as plain text  
Dear MySQL users,

MySQL Connector/Java 8.0.9-rc is the first Release Candidate
of the 8.0 branch of MySQL Connector/J, providing an insight into
upcoming features. It is suitable for use with MySQL Server versions
5.5, 5.6, 5.7, and 8.0. It supports the Java Database Connectivity
(JDBC) 4.2 API.

This release includes the following new features and changes, also
described in more detail on

MySQL Connectors and other MySQL client tools and applications now
synchronize the first digit of their version number with the (highest)
MySQL server version they support.
This change makes it easy and intuitive to decide which client version
to use for which server version.

As always, we recommend that you check the "CHANGES" file in the download
archive to be aware of changes in behavior that might affect your

Changes in MySQL Connector/J 8.0.9 (2018-01-30, Release

    Functionality Added or Changed

      * X DevAPI: In the process of refining the definition of
        the X DevAPI to cover the most relevant usage scenarios,
        the following API components have been removed from the X
        DevAPI implementation for Connector/J:

           + Components that support DDLs for views, including
             the createView(), dropView(), and modifyView()

           + Components that support DDLS for tables, including
             the createTable(), dropTable(), and modifyTable()

           + Components that support session configurations,
             including the SessionConfig object, the
             PersistenceHandler interface, the PasswordHandler
             interface, and the SessionConfigManager class.

      * X DevAPI: Added the setSavepoint(), rollbackTo(), and
        releaseSavepoint() methods to the Session interface to
        support the SAVEPOINT
        statements. See MySQL Connector/J X DevAPI Reference
        ( for more

      * X DevAPI: A new patch() function has been added to the
        ModifyStatement interface. The function accepts an
        JSON-like object describing document changes and applies
        them to documents matched by the modify() filter. See
        MySQL Connector/J X DevAPI Reference
        ( for more

      * X DevAPI: The createIndex() method for the Collection
        interface now has a new syntax. See MySQL Connector/J X
        DevAPI Reference
        ( for more

      * X DevAPI: Added the following methods for single-document
        operations in the X DevAPI:

           + replaceOne()

           + addOrReplaceOne()

           + getOne()

           + removeOne()
        See MySQL Connector/J X DevAPI Reference
        ( for more

      * X DevAPI: Setters and getters methods have been added for
        the configuration properties with the MysqlDataSource,
        MysqlXADataSource, and MysqlConnectionPoolDataSource

      * X DevAPI: The connection property enabledTLSProtocols can
        now be used to select the allowed TLS versions for an X
        Protocol connection to the server.

      * Connector/J now supports the new caching_sha2_password
        authentication plugin, which is the default
        authentication plugin for MySQL 8.0.4 and later (see
        Caching SHA-2 Pluggable Authentication
        gable-authentication.html) for details).
        To authenticate accounts with the caching_sha2_password
        plugin, either a secure connection to the server using
        or an unencrypted connection  that supports password exchange
        using an RSA key pair (enabled by setting one or both of the
        connecting properties allowPublicKeyRetrieval and
        serverRSAPublicKeyFile) must be used.
        Because earlier versions of Connector/J 8.0 do not
        support the caching_sha2_password authentication plugin
        and therefore will not be able to connect to accounts
        that authenticate with the new plugin (which might
        include the root account created by default during a new
        installation of a MySQL 8.0 Server), it is highly
        recommended that you upgrade now to Connector/J 8.0.9, to
        help ensure that your applications continue to work
        smoothly with the latest MySQL 8.0 Server.

      * Connector/J now takes advantage of the MySQL Server 8.0
        data dictionary by making the connection property
        useInformationSchema true by default; this makes
        Connector/J, by default, access the data dictionary more
        efficiently by querying tables in the INFORMATION_SCHEME.
        See INFORMATION_SCHEMA and Data Dictionary Integration
        for details. Users can still set useInformationSchema to false,
        but for MySQL 8.0.3 and later, some data dictionary queries might
        then fail, due to deprecations of older data dictionary features.

      * In the past, query texts were always passed as strings to
        QueryInterceptor methods, even if the texts were not
        actually used by them. Now, only suppliers for the texts
        are passed, and the texts are only extracted by get()
        calls on the suppliers.

    Bugs Fixed

      * The connection property nullNamePatternMatchesAll, when
        set to false (which was the default value), caused some
        DatabaseMetaData methods to throw an error when a null
        search string was used with them. The behavior was not
        compliant with the JDBC specification, which requires
        that a search criterion be ignored when a null search
        string is used for it. The connection property has now
        been removed from Connector/J 8.0. (Bug #26846249, Bug

      * Trying to print the query in a PreparedStatement using
        the toString() method after it has been closed resulted
        in an exception (No operations allowed after statement
        closed) being thrown. (Bug #26748909)

      * When working with MySQL Server 8.0, an update or delete
        statement for a CONCUR_UPDATABLE ResultSet failed when
        the ResultSet's primary keys included a boolean column
        and the character set used was not latin1. (Bug

      * Connector/J failed to recognize a server greeting error
        it received during a handshake with the server and parsed
        the error message as a normal greeting packet, causing an
        ArrayIndexOutOfBoundsException to be thrown. (Bug
