very very strange ODBC error

[LongNeckDeer]

I am testing using JDBC-ODBC bridge and I get a very troubling bug
my function for output are as follows

public void getOutput() throws SQLException {

String sql = "SELECT * FROM Neuron";
rs = stmtN.executeQuery(sql);

while (rs.next()) {
String output = Integer.toString(rs.getInt(1))+": "+rs.getString(2);
System.out.println("Program output: "+output);
}

}

Program output: 0: there
Program output: 1: hello
Program output: 2: not
Program output: 3: this
Program output: 4: could
Program output: 5: be
Program output: 6: good
Program output: 7: I
Program output: 8: am

and the program works fine about three out of four
and it can throws SQLException any time in the program...
and I can't find anything strange in the content of the database...
I definately needs some help...

I am using Access2000 and code for DB are as follows
try {
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
conN = DriverManager.getConnection("jdbc:odbc:Neuron","lib", "lib" );
stmtN = conN.createStatement();
conL = DriverManager.getConnection("jdbc:odbc:Link","lib", "lib" );
stmtL = conL.createStatement();

}

thank you for reading and answering my problem :)
