Environment:JRuby 1.7/9k
org.bson.ByteBuf#getInt64 method should not return Bignum when it
is in range covered by Fixnum (long is always covered by Fixnum).
On MRI it is not possible to create Bignum in range of Fixnum,
but Java extension does it:
https://github.com/mongodb/bson-ruby/blob/master/src/main/org/bson/ByteBuf.java#L261
It wont be fixed on JRuby.
This leads to unexpected behaviour: http://pastie.org/10978801#1,14,17,19,25
