Column names are not guaranteed in order for getColumnNames of OracleManager

OracleManager uses the following query to retrieve column names:
public static final String QUERY_COLUMNS_FOR_TABLE =
"SELECT COLUMN_NAME FROM ALL_TAB_COLUMNS WHERE "
+ "OWNER = ? AND TABLE_NAME = ?";

However, it does not guarantee the order of the returned column names
unless a "ORDER BY" is specified. This may not work properly for newer
version of Oracle.
