What you said is correct in general. But in case of our code we can see
places where we catch runtime exceptions and fail without giving out the actual
reason. If we think the reason is of no use to the user, we should simply
bubble them up and handle them accordingly in the top most calling method. If
we think the reason is not of importance to the user, we can simply log it and
then send appropriate error messages.
In the current code i wanted to force people to bubble up the runtime
exceptions as well and then take a call at the top most calling method. This
way if something fails we do not see multiple exception messages one for each
level at which the failure occurred and with different error messages leading
to confusion.
