I'm mostly in agreement here, but it isn't enough for me to roll back. While developing, I sometimes use the debugging info but I'm not a huge fan of the debugger since it slows things down.
I understand what you mean about line numbers, but as Erel said in another thread, you can often figure out where the problem is, and so long as you backup your objects folder with each version you release, you also have the option of looking at the java source code, which should definitely point you to the problem.
