ConcurrentModificationException on "rake test" in Rails 3.0.3
-------------------------------------------------------------
Key: JRUBY-5209
URL: http://jira.codehaus.org/browse/JRUBY-5209
Project: JRuby
Issue Type: Bug
Affects Versions: JRuby 1.5.5
Environment: Rails 3.0.3, on Java jdk1.6.0_22 on Linux
Reporter: Anders Bengtsson
Assignee: Thomas E Enebo
JRuby aborted with this stacktrace when running "rake test" on a small Rails
project. It consistently fails on one Linux server, but works on other Linux
and Mac systems.
Someone is complaining about something similar in the comments here, also tests
in Rails 3.0.3:
http://weblog.rubyonrails.org/2010/11/15/rails-3-0-3-faster-active-record-plus-plenty-of-fixes
Maybe I'll be able to provide some of the Ruby code causing it later.
