At run time, if driver cannot read the messages property file, the driver uses the message portion
of the property as the text of the message. For a description of the message portion, see the
Localized-Message String Format.
At run time, if the Type 4 driver cannot read the messages property file, it sets the locale to English
locale, thereby loading the default properties file that is shipped with the Type 4 Driver. The default
properties file, SQLMXMessages_en.properties, fetches the error messages and status
messages.
