Installing the Gliffy Plugin fails when database is MySQL

The following exception is raised when installing the Gliffy Plugin for Confluence using Confluence 2.3.1 and MySQL.

The error seems to only show up when using the mysql-connector-java-3.1.10 database driver.
When I upgraded to mysql-connector-java-5.0.4, the install was successful.

Cause:
java.lang.RuntimeException: There was a problem evicting or flushing a PluginData object
at com.atlassian.confluence.plugin.persistence.hibernate.HibernatePluginDataDao.saveOrUpdate(HibernatePluginDataDao.java:65)
caused by: net.sf.hibernate.exception.GenericJDBCException: Could not execute JDBC batch update
at net.sf.hibernate.exception.ErrorCodeConverter.handledNonSpecificException(ErrorCodeConverter.java:90)
caused by: com.mysql.jdbc.PacketTooBigException: Packet for query is too large (1048592 > 1048576). You can change this value on the server by setting the max_allowed_packet' variable.
at com.mysql.jdbc.MysqlIO.send(MysqlIO.java:2632)
