>> why are there more defects in Erlang and Java than Perl and Ruby? I have no experience with Erlang, but one reason I'd expect Java to have more defects than Ruby and Perl is that Java is more verbose, i.e. it takes more code to get something done. One would naively expect to find an association between the size of commits and their propensity to contain errors.
