对象实例会发生一些内存泄漏吗?

我找到了一个用于jdbc操作的实用程序类。

public ResultSet executePreparedStatementQuery(String sql, ArrayList args)
        throws ValidationException {

    try {
        InitialContext ctx = new InitialContext();
        DataSource ds = getDataSource(ctx);
        conn = ds.getConnection();
        CustomLogger.getLogger("JDBCUtility").logConnection(conn, true, 3);
        pStmt = conn.prepareStatement(sql);

        int count = 1;
        Iterator iter = args.iterator();
        while (iter.hasNext()) {
            Object obj = iter.next();
            setPreparedStatementField(count, obj);
            count++;
        }
        rs = pStmt.executeQuery();

    } catch (SQLException sqlEx) {
        close();
        throw new ValidationException(sqlEx.getMessage());
    } catch (Exception cnfe) {
        close();
        cnfe.printStackTrace();
        throw new ValidationException(cnfe.getMessage());
    }

    return rs;
}

所有的连接,语句和结果集都是由非静态类变量引用的。这会在anather类中创建一些JDBCUtility实例(dbutil)后调用rs = dbutil.executePreparedStatementQuery(strQuery, values);时泄漏内存吗?

提前谢谢..!
