Inconsistent handling of Fixnum/Bignum boundary
-----------------------------------------------
Key: JRUBY-4109
URL: http://jira.codehaus.org/browse/JRUBY-4109
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.3.1
Environment: jruby 1.3.1 (ruby 1.8.6p287) (2009-07-10 6586) (Java
HotSpot(TM) Client VM 1.6.0_15) [i386-java]
Reporter: Alex Coles
I realize the boundaries between Fixnum/Bignum are different between JRuby and
MRI (http://jira.codehaus.org/browse/JRUBY-1587), however the boundaries appear
to be inconsistent:
{{
[alexbco...@mondiale ~]$ jirb
irb(main):001:0> -9223372036854775808.class
=> Bignum
irb(main):002:0> "-9223372036854775808".to_i
=> -9223372036854775808
irb(main):003:0> "-9223372036854775808".to_i.class
=> Fixnum
}}
{{
[alexbco...@mondiale ~]$ irb
>> -9223372036854775808.class
=> Bignum
>> "-9223372036854775808".to_i
=> -9223372036854775808
>> "-9223372036854775808".to_i.class
=> Bignum
}}

This is causing an issue in one of our DataMapper tests where we call eql? on a
DataMapper model with an Integer property and compare the original and the
serialized/deserialized property. See http://gist.github.com/212127
