With this change, we will first check if this property has been explicitly set. If explicitly set, then we'll use that value. Otherwise, we will default back to querying the database to determine whether to support delimited identifiers or not. > Here's an example of the property to set to turn off the delimited identifier support: > -- This message is automatically generated by JIRA.
