Dear MySQL users,

MySQL Connector/J Version 8.0.14 is the GA release of the 8.0

Connectivity (JDBC) 4.2 API, and implements the X DevAPI.

This release includes the following new features and changes, also

https://dev.mysql.com/doc/relnotes/connector-j/8.0/en/news-8-0-14.html

As always, we recommend that you check the "CHANGES" file in the

Changes in MySQL Connector/J 8.0.14 (2019-01-21, General
Availability)

      * Functionality Added or Changed

      * Bugs Fixed

Functionality Added or Changed


      * Important Change: For MySQL Server 8.0.14 and later,
        5.7.25 and later, 5.6.43 and later, and 5.5.63 and later,
        minimal permissions on named pipes are granted to clients
        that use them to connect to the server. Connector/J,
        however, can only use named pipes when granted full
        access on them. As a workaround, the MySQL Server that
        Connector/J wants to connect to must be started with the
        system variable named_pipe_full_access_group; see the
        description for the system variable for more details.
        (Bug #28971500)

      * X DevAPI: getDefaultSchema() now returns null when no
        default schema has been set for the Session.

      * Connector/J now has a new property for building from
        source, com.mysql.cj.build.verbose, which controls the
        verbosity of the build process' output. Its default value
        is false, which makes the output considerably shorter
        comparing with earlier versions of Connector/J.
        (Bug #28970166)

      * The method ResultSet.getBoolean() now returns FALSE when
        the designated column is of data type CHAR or VARCHAR and
        contains an "N" or "n". This makes Connector/J 8.0
        behaves like Connector/J 5.1 when it comes to converting
        strings to booleans. (Bug #28706219, Bug #92574)

      * Connector/J is now capable of reading and, if needed,
        ignoring any initial notice packets sent by X Plugin
        before an X Protocol connection is established.

Bugs Fixed


      * X DevAPI: Connector/J returned a NullPointerException
        when an application tried to establish an XProtocol
        connection using a Windows named pipe, which is not
        supported. With this fix, an XProtoclException is
        returned instead.
        This fix also makes sure that instead of a
        NullPointerException, a proper exception is thrown when
        an application tries to establish a Classic MySQL
        Protocol connection with a named pipe, but the named pipe
        is not specified at connection or it cannot be found on
        the specified path. (Bug #28606708)

      * X DevAPI: Adding an empty document with executeAsync()
        resulted in an ERROR 5013 (Missing row data for Insert).
        With this fix, no error or warning is returned in the
        case. (Bug #23045642)

      * Collection.count() returned a wrong error message when
        the collection did not exist. (Bug #28924137)

      * The source code of Connector/J contains non-ASCII
        characters, which might cause encoding issues during
        compilation if the system did not also use a UTF-8
        locale. With this fix, the build script now handles
        non-ASCII characters well regardless of the system
        locale. (Bug #28894344)

      * A memory leak occurred if Connector/J was loaded via the
        bootstrap class path instead of the main application
        classpath. It was because
        AbandonedConnectionCleanupThread failed to initialize its
        internal thread in that case, so that references for
        closed connections were not cleaned up, and their number
        kept growing. This fix repairs the clean up process for
        closed connections and also makes the process thread
        safe. (Bug #28747636, Bug #92508)

      * clearInputStream() returned a NullPointerException when
        the mysqlSocket, mysqlInput, or mysqlOutput object it
        tried to retrieve was null. With this fix, an IOExcpetion
        is thrown instead in the situation. Thanks to Henning
        Schmiedehausen for contributing to the fix.
        (Bug #28731795, Bug #92625)

      * Updating a result set returned by a server-side prepared
        statement with SELECT ... FOR UPDATE
        (http://dev.mysql.com/doc/refman/8.0/en/select.html)
        resulted in an SQLException. (Bug #28692243, Bug #92536)

      * When the connection property zeroDateTimeBehavior was set
        to CONVERT_TO_NULL, Connector/J converted a TIME
        (http://dev.mysql.com/doc/refman/8.0/en/time.html) type
        value of 00:00:00 to null. With this fix, it returns a
        java.sql.Time instance of zero hours, minutes, and
        seconds, as expected. (Bug #28101003, Bug #91065)

      * When using server-side prepared statements and working
        with a table with multicolumn primary key, an updateRow()
        call failed with a NullPointerException or a
        SQLException. (Bug #25650514)

      * When using server-side prepared statements, a
        refreshRow() call after an updateRow() call failed with a
        SQLException. (Bug #25650482)

      * changeUser() failed to change or reauthenticate a user
        when all of the following were true: (a) connection to
        the server was by SSL; (b) the caching_sha2 or
        sha256_password authentication plugin was used for the
        user; and (c) the user password contained Unicode
        characters. (Bug #25642226)
