It isn't just Java where the half open interpretation might be expected. 
I think that would be the expectation in many C derived languages. There 
is also a family of languages where closed intervals are normal 
(Fortran, Pascal, etc). Either be explicit about inclusion or accept 
that Java is a member of the half open group of languages.

Incidentally, mathematicians might expect (1,10) to mean the set that 
excludes both ends!
