How do I setup Eclipse to stop on the line an exception occured?

Question

Hi,

How can I setup Eclipse to stop at the point an exception occurred.

I have an Eclipse breakpoint setup to break on an exception. In the code example below, the problem I'm having is Eclipse tries to open the Integer source code. Is there any way to just have debugger break at the point shown in my code example? If I move down the stack trace, I will get to this line, it'd be nice if there's a way to do this without the "Source not found" window coming up.

This can be done in Visual Studio, so it's driving me crazy not being able to find a way to do this in Eclipse.

package com.test;

public class QuickTest
{
  public static void main(String[] args)
  {
    try
    {
        test();
    }
    catch(NumberFormatException e)
    {
        System.out.println(e.getMessage());
    }
 }

  private static void test()
  {
    String str = "notAnumber";

    Integer.parseInt(str);//<----I want debugger to stop here
  }
}

Answer 1

1. Can't you just set a breakpoint on the Integer.parseInt(str) line?
2. If you point your Eclipse project at using a JVM JDK instead of a JRE it should pick up the source code for all of the platform classes (Integer etc).

Answer 2

Preferences -> Java -> Debug -> Step Filtering Choose packages you want to filter out when debugging (java.*, sun.*, etc) On debug make sure the little step filtering arrow is selected.

This should do the trick.

Answer 3

The Debug view will show the entire stack of the current execution. You need to select the line you want to see. It will be same as you had a breakpoint there, you can see all the variables etc.

Answer 4

I'm not sure how else to get there, but I just do:

Window -> Show View -> Breakpoints

And in that tab there is a "J!" that lets you set breakpoints on exceptions.
