Originally reported on nbusers by Thomas Kellerer:
I tried it with the following class:

public class MyTest {
    public static void main(String[] args)	{
	String s = null;
        s = s.replace('.',',');
    }
}

which produces a null pointer exception. But I cannot 
jump to that line (the source is obviously mounted :-)

I have tested it on three different W2K computers
now, one 
having JDK 1.4.0 the others with JDK 1.4.0_01 and
I can never jump to the source, although the lines
are displayed as hyperlinks :-(
