Hi all,
I tested JRuby trunk on Rails 2.0 PRE1 with an JRoR application which
uses ActiveResource, and found some weird behavior.
First of all, download the application from http://ias.springnote.com/pages/512602/attachments/226453
(or open http://ias.springnote.com/pages/512602.xhtml and click
rails2_ares_test.zip link)
Next, unzip it and run "jruby script/server".
Access http://localhost:3000/ with your browser and you can see a
list. This causes "Page" resource to do "find :all", which works fine.
Meanwhile, access http://localhost:3000/pages/4434 and you might see
Home
or the following error message:
---
NoMethodError in PagesController#show
You have a nil object when you didn't expect it!
The error occurred while evaluating nil.attributes

If you see either "Home" or the error message, please repeat
refreshing your browser with F5 or CTRL(Command)+R, then you can see
the other result. In case the error occurs, connection.rb shows that
status 200 and length 0 in its info logging.
I tested this application with MRI and it worked well with both http://localhost:3000/pages
and http://localhost:3000/pages/4434
What I guess about this discrepancy is that HTTPS connection in JRuby
may have some problem.
Thanks in advance for your help,
