This class maintains a physical database connection which is passed to each StandardXAConnectionHandle when it is created. It is the StandardXAConnectionHandle object which the application receives and which it perceives as the java.sql.Connection object. StandardXAConnectionHandle objects pass PreparedStatements back to the StandardPooledConnection so that they can be retained across StandardXAConnectionHandle instantiations.
