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::PrivateType: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.

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](http://jira.codehaus.org/browse/JRUBY-3423)

Thank you!
