   <P>
   This is a vacuous, deprecated class. At one time, it had real behavior and helped us support
   separate data sources for Java 5 and Java 6.
   Now that we no longer support Java 5, all functionality has migrated into the superclass, EmbeddedConnectionPoolDataSource.
   This class is preserved for backward compatibility reasons.
   </P>
   @deprecated Use {@link EmbeddedConnectionPoolDataSource} instead.
