/**
 * The class {@code FBDataSource} is a ConnectionFactory for jdbc Connection objects. All work is delegated to a
 * XcaConnectionManager.
 * 
 * This data source is for internal use inside Jaybird. For a simple data source, use
 * {@link org.firebirdsql.ds.FBSimpleDataSource}, for XA {@link org.firebirdsql.ds.FBXADataSource}.
 * 
 * 
 * If you need a standalone connection pool, consider using a connection pool implementation like HikariCP, c3p0 or
 * DBCP.
