I assume you are talking about getCoveredText() now?  The current
code, as Tommaso observes, will throw an exception when the offsets
are invalid.  To my taste, that is the correct behavior, although
it could be argued that we should throw our own exception there.
I also agree that the cases where it returns null should be

I was arguing against checking for validity of offsets when
annotations are created.  That might break existing code, as you

So if you ask me, the current behavior of getCoveredText() is
fine, it just needs to be documented.
