This looks to be a method matching bug.
'abc'.substring(0,1+1) is empty
'abc'.substring(0,2) gives ab as expected.
The problem seems to be the fact that the result of 1+1 (or any arithmetic operation) is a Long and that
long cannot be fed into substring but no attempt to cast the Long to int is done.
