JRE检测到由连接方法引起的致命错误

Question

我的程序在执行此语句时遇到致命错误，就像循环第二次执行此语句Statement stmt = conn.createStatement();一样。是什么原因造成的？是否不允许通过方法传递连接？程序运行通过这个循环：

Connection conn = open_connection();
for(int aa = 0;aa<symbols.length;aa++){
    String[][] dub_array = parse(symbols[aa]);
    autowave(dub_array,19,14,symbols[aa],conn);
}

open_connection看起来像这样：

public static Connection open_connection() throws Exception{
    Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
    String sDBQ = "C:/Documents and Settings/mike/Desktop/stock/data/AW.mdb";
    String database = "jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ=" + sDBQ + ";DriverID=22;READONLY=false";
    Connection conn = DriverManager.getConnection( database ,"","");
    return conn;
}

错误如下：

我的程序在像第二次循环执行此语句语句stmt=conn.createStatement（）；autowave（dub_array，19,14，symbol[aa]，conn）；尝试在循环之前只创建一个语句对象，然后在循环中使用它。带有MS Access的JdbcOdbcDriver是蹩脚的，有时会遇到意外问题。
