Jruby yaml load issue with floats?

[Pradeep Gatram]

Try this with both MRI and Jruby 1.1.6 (with active support 2.2.2)

irb(main):004:0> require 'rubygems'
=> true
irb(main):005:0> require 'activesupport'
=> true
irb(main):006:0> YAML.load(YAML.dump(3.0)).eql?(3.0)
=> true

MRI returns true, while JRuby returns false !!!

The root cause is that JRuby is loading the yaml as
irb(main):021:0> YAML.load(YAML.dump(3.0))
=> #<YAML:rivateType:0x18ad9a0 @value="3.0", @type_id="tag:yaml.org,
2002:float:Float">

instead of as 3.0

Has any bug been logged for this? I would have gone ahead and logged
it, but I am unable to register on codehaus . For some wierd reason,
I just can't get thru their capta!!! (another bug???).

Would be great if someone could log this one as a bug or point me to
an already logged bug or otherwise explain this behaviour.

This should be fixed on trunk/1.2. Can you test out a nightly build?

Charles,

Its still an issue on the 1.2 nightly build.

pradeep@pradeep-laptop:~/jruby-1.2.0/bin$ ./jruby -S irb
irb(main):001:0> require 'rubygems'
=> true
irb(main):002:0> require 'activesupport'
JRuby limited openssl loaded. gem install jruby-openssl for full
support.

=> true
irb(main):003:0> YAML.load(YAML.dump(3.0))
=> #<YAML:rivateType:0x2d80ae @type_id="tag:yaml.org,
2002:float:Float", @value="3.0">
irb(main):004:0> YAML.load(YAML.dump(3.0)).eql?(3.0)
=> false
irb(main):005:0>

Charles,

Ahh, so it is. It's something specific to running with ActiveSupport
present, because it works fine with normal Ruby.

I've filed it here: http://jira.codehaus.org/browse/JRUBY-3423

Thank you!
