Grails transaction setSavePoint method on mysql causes exception

I am using grails with mysql 5. I am using .withTransaction for transaction management in a service. Within the withTransaction block I am using savePoint() method which is causing the following exception. Note: I am using setRollbackOnly() method without any issue.

By default the transaction manager for hibernate and MySQL don't have the save points enabled.

In BootStrap.groovy add the following:

transactionManager.setNestedTransactionAllowed(true)

Then in a transaction you can do the following:

Thing.withTransaction { status ->
  //Do some work and a save
  def savePoint = status.createSavepoint()
  //do other work
  if(checkOk)
  {
    //Everything worked so don't need the save point anymore
    status.releaseSavepoint(savePoint)
  }
  else
  {
    //The other work did not work so rollback from it.
    status.rollbackToSavepoint(savePoint)
  }

}
