Unstable behavior with ARes in Rails 2.0 PRE1
---------------------------------------------
Key: JRUBY-1404
URL: http://jira.codehaus.org/browse/JRUBY-1404
Project: JRuby
Issue Type: Bug
Environment: Mac OS X 10.5 9A559
java version "1.6.0_01-dp"
Java(TM) SE Runtime Environment (build 1.6.0_01-dp-b06-77)
Java HotSpot(TM) 64-Bit Server VM (build 1.6.0_01-35-release, mixed mode)
Reporter: Changshin Lee
Assignee: Thomas E Enebo
I tested JRuby trunk on Rails 2.0 PRE1 with an JRoR application which uses
ActiveResource, and found some weird behavior.
To reproduce the behavior,
1. 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)
2. Unzip it and run "jruby script/server".
3. Access http://localhost:3000/ with your browser and you can see a list. This
causes "Page" resource to do "find :all", which works fine.
4. 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.
