View as plain text  
Hello all,

MySQL Connector/J 5.1.25, a maintenance release of the production
5.1 branch has been released. Connector/J is the Type-IV pure-Java
JDBC driver for MySQL.

Version 5.1.25 is suitable for use with many MySQL server versions,
including 4.1, 5.0, 5.1, 5.4, 5.5 and 5.6.

It is now available in source and binary form from the Connector/J
download pages at
http://dev.mysql.com/downloads/connector/j/5.1.html
and mirror sites as well as Maven-2 repositories.

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 application.

MySQL Connector/J 5.1.25 includes the following general bug fixes
and improvements, also listed in more detail on
http://dev.mysql.com/doc/relnotes/connector-j/en/news-5-1-25.html

Changes in MySQL Connector/J 5.1.25 (01 May 2013)

Bugs Fixed

   * The getDriverName() function would return "MySQL-AB JDBC
     Driver" as the driver name. This fix changes the driver name
     string to "MySQL Connector Java". (Bug #16436511)

   * An exception occurred if NULL was passed to a stored procedure
     INOUT parameter. (Bug #60816, Bug #12800874)

   * The "mysql-connector-java-5.1.24.jar" prepared for maven.org
     contained the artifact, META-INF/INDEX.LIST, which incorrectly
     pointed to "mysql-connector-java-5.1.24-bin.jar". For
     Connector/J 5.1.25, META-INF/INDEX.LIST has been corrected and
     now points to "mysql-connector-java-5.1.25.jar".
     The work around for "mysql-connector-java-5.1.24.jar" prepared
     for maven.org is to rename the JAR file to
     "mysql-connector-java-5.1.24-bin.jar" or to download the MySQL
     Connector/J 5.1.24 driver from
     http://dev.mysql.com/downloads/connector/j/. (Bug #68801, Bug
     #16574419)

   * ReplicationConnection.isMasterConnection(), which is intended
     to check if the current connection is the master connection,
     would always return "false". This fix implements logic that
     returns "true" if the current connection is the master
     connection. (Bug #68763, Bug #16545334)

   * When using Connector/J in a replication deployment, all of the
     slave connections would not be pinged. This fix ensures that
     all active physical connections to slaves are pinged, and that
     communication exceptions are thrown if:

        + The master connection ping fails, and the connection is
          currently set to use the master connection via
          Connection.setReadOnly(false).

        + The Connection object is set to use the slave via
          Connection.setReadOnly(true), and the currently-selected
          slave connection ping fails.
     (Bug #68733, Bug #16526938)

   * Tomcat would fail to stop abandoned connection cleanup
     threads. The fix for Bug#65909 introduced the ability to stop
     daemon threads started by the Connector/J driver but it also
     cleared references from daemon threads to the parent
     classloader. When the clearReferencesStopThreads property is
     set to "true" in context.xml, Tomcat analyzes classloaders to
     detect and stop lost threads. This fix ensures that abandoned
     connection cleanup threads retain a reference to the parent
     classloader. (Bug #68556, Bug #16443387)

   * Producing Connector/J JAR packages in Eclipse using Ant tasks
     would result in a JAR file without compiled class files.
     Compile-related tasks in the Ant script would direct
     compilation targets to the bin directory (for Eclipse
     compatibility), while JAR related tasks were directed to
     {buildDir}/${fullProdName}. This fix changes the JAR task
     reference to ${compiler.output} instead of
     {buildDir}/${fullProdName}. (Bug #68664, Bug #16486957)

   * When connecting to a MySQL 5.6 server, Connector Java will now
     send connection attributes which are exposed in relevant
     PERFORMANCE_SCHEMA tables.  By default, the following attributes
     are sent:

      _client_version: version number of MySQL Connector Java
      _client_name: "MySQL Connector Java"
      _client_license: "commercial" or "GPL", depending on the build used
      _runtime_vendor: JVM vendor name
      _runtime_version: JVM version

     The default attributes may also be augmented with user-defined
     key/value pairs, specified in the new connectionAttributes property
     (ex: connectionAttributes=key1:val1,key2:val2).  The default
     attributes may also be suppressed entirely by setting
     connectionAttributes property to "none".
