Eclipse debugging "source not found"

I just started using Eclipse so go easy on me ;). But when trying to debug a JUnit test case I get a dialog that states the the source is not found when I get to this line in the code in my test method:

Assert.assertEquals(1, contents.size());

I know I should probably go and try and download the source from somewhere, but I really don't want to because I have no interest in stepping into the JUnit code. I have the JUnit runtime jar so Why does Eclipse expect me to have all the referenced tools source code in order to debug my own code (seems somewhat silly)?

My main question is though, how can I tell Eclipse to skip this dialog when the source is not available and allow me to continue to debug my own code?

[Edit]

I've isolated the cause of this. It seems that Eclipse seems to think it needs the source when an exception is thrown by the internal JUnit code. In general is there anyway to tell it that it doesn't and just have it throw up an error dialog of some kind instead?

The debug callstack will display a JUnit source code line when throwing an exception.
But you should not need to worry about that, if you do not have the source code of JUnit.

If you go back one line in the callstack, you should see the line (of your source code) which has caused the JUnit exception.
That should be enough to debug your code.

To associate the source with JUnit, you could add the junit.jar in the librairies of your project, and associates the junit-x.y.z-src.jar to the junit-x.y.z.jar, like so:

That will generate in the .classpath of your project a line like:

<classpathentry kind="lib" path="junit-x.y.z.jar" sourcepath="junit-x.y.z-src.jar">

Note: actually, there would be the full path of the junit[...].jar files in this classpathentry line. But you could also use Linked resources to avoid that fixed value (the full path) in your .classpath file.

Calculate contents.size() on a separate line instead or set a breakpoint on the method.

Also note the junit view in Eclipse allows you to navigate the stack trace.
