When I try to start my grails application, I get the following error with partial stacktrace):


Code:

       <snipped>
The relevant datasource is:


Code:
environments {
	development {
		dataSource {
			logSql = false
			dbCreate = "create-drop" // one of 'create', 'create-drop','update'
			dialect=org.hibernate.dialect.MySQL5InnoDBDialect
			url = "jdbc:mysql://localhost:3306/plover_development?tcpKeepAlive=true"
		}
	}
I am running mySQL 5.5.24 and the driver is mysql-connector-java:5.1.18. It is an older driver, but it is compatible with mySQL 5.5.

Anyone else encountered a similar problem in the past?
