OK. I understand. Until we have a good exception system I will just
define a few new exceptions in the same way as it is done now.

Why checked exceptions?
I don't want to start yet another discussion on checked vs non-checked
exceptions in general since it often goes into discussing
personal preferences. However, as you wrote, there are also some
practical issues with checked exceptions like calling a method
that throws a checked exception inside the hasNext() method of
an Iterator. It often leads to wrapping the checked exception into
another exception without any added value.

I am willing to spend some effort on this topic.
