Trailing underscores handling in String's to_i different from MRI
-----------------------------------------------------------------
Key: JRUBY-5017
URL: http://jira.codehaus.org/browse/JRUBY-5017
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.4
Reporter: Robin Salkeld
Similar to JRUBY-4424, but probably a different cause. In this case this
expression:
"1_".to_i
...will produce a Fixnum in MRI ruby, but a Bignum in JRuby 1.4.
Annoying since this means the set of migrated versions for a Rails plugin
returns an array of Bignums, which don't compare eql? to Fixnums and hence
messes up my custom migrations logic. :)
Note that the test cases added for JRUBY-4424 would catch this problem if they
were more specific about the expected class. As they are they use == and hence
don't notice the difference.
