An incompatibility with newer C3P0 libraries and the version of the MySQL JDBC driver that was downloaded for use with Bamboo.
Resolution
Download a more recent version of the MySQL JDBC driver: https://dev.mysql.com/downloads/connector/j/
At the time of writing this issue presented on Bamboo 5.15.3 with MySQL Java connector 5.1.20 and can be resolved by updating it to 5.1.41. For more information on how to install the MySQL JDBC driver for use with Bamboo please refer to the following documentation: Connect Bamboo to a MySQL database
