[java] What is IllegalStateException?

I am trying to use the following Fastload API

connection ... etc is perfect.

I know exactly where it fails

 ...........
 System.out.println(" Streaming " + dataFile);
 pstmtFld.setAsciiStream(1, dataStream, -1); // This line fails
 System.out.println("check the above line"); // This does not go to console
 ...........

Exception is

Exception in thread "main" java.lang.IllegalStateException: Sample failed.

[ODBC Teradata Driver] Invalid precision: cbColDef value out of range

Here is my table that I am trying to upload. It is a .csv format and when I open it via notepad it look like this

1,9,Win
2,9,Winc
3,9,Wi

Why do I get this exception? How can I improve it? As far as I understand the problem is pstmtFld.setAsciiStream(1, dataStream, -1); does not accept the dataset somehow and throw an exception

Illegal State Exception is an Unchecked exception.

It indicate that method has been invoked at wrong time.

example:

Thread t = new Thread();
t.start();
//
//
t.start();

output:

Runtime Excpetion: IllegalThreadStateException

We cant start the Thread again, it will throw IllegalStateException.

package com.concepttimes.java;

import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;

public class IllegalStateExceptionDemo {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        List al = new ArrayList();
        al.add("Sachin");
        al.add("Rahul");
        al.add("saurav");
        Iterator itr = al.iterator();  
        while (itr.hasNext()) {           
            itr.remove();
        }
    }
}

IllegalStateException signals that method has been invoked at the wrong time. In this below example, we can see that. remove() method is called at the same time element is being used in while loop.
