YAML messes up custom tag
-------------------------
Key: JRUBY-2976
URL: http://jira.codehaus.org/browse/JRUBY-2976
Project: JRuby
Issue Type: Bug
Components: Miscellaneous
Affects Versions: JRuby 1.1.4
Reporter: Michael S. Allman
Consider the following jirb transcript:
irb(main):001:0> require 'yaml'
=> true
irb(main):002:0> class Person
irb(main):003:1> yaml_as 'tag:data.allman.ms,2008:Person'
irb(main):004:1> end
=> Person
irb(main):005:0> p = Person.new
=> #<Person:0x55bfaf>
irb(main):006:0> p.to_yaml
=> "--- !data/Person {}\n\n"
irb(main):007:0>
When Person p is serialized, the yaml tag is shortened to !data/Person. This
is not correct. Consider the identical script run with plain irb (not JRuby):
>> require 'yaml'
=> true
>> class Person
>> yaml_as 'tag:data.allman.ms,2008:Person'
>> end
=> Person
>> p = Person.new
=> #<Person:0x5bc818>
>> p.to_yaml
=> "--- !data.allman.ms,2008/Person {}\n\n"
Here the tag is written as !data.allman.ms,2008/Person, which I believe is
correct.
Because JRuby messes up the custom tag, it can't deserialize the YAML with the
correct type.
I will work on a patch to fix this issue.
