Poolman/mySQL transaction exception on connect

I am trying to load my mySQL JDBC driver using poolman and
am getting the following error:
 openConnection() - Exception occurred: SQLException occurred in 
JDBCPool: java.sql.SQLException: Transaction Isolation Levels are not 
supported.

I am using the max version of mySQL and created the tables I am trying 
to access as InnoDB tables.
Any reason why the driver is throwing the exception?

Thanks.
