LoadError: load error: bundler/definition -- java.lang.NoClassDefFoundError: Could not initialize class org.jruby.javasupport.JavaClass

whoops, forgot to include java version:
java version "1.6.0_29"
Java(TM) SE Runtime Environment (build 1.6.0_29-b11-402-11D50)
Java HotSpot(TM) 64-Bit Server VM (build 20.4-b02-402, mixed mode)

Why do you have jruby-jars?

A plain Rails 3.0.10 app seems to work for me.

$ jruby --1.9 -v script/rails s
jruby 1.6.6 (ruby-1.9.2-p312) (2012-01-30 5673572) (Java HotSpot(TM) 64-Bit Server VM 1.6.0_29) [darwin-x86_64-java]

We have jruby-jars because we are using warbler to deploy this as a standalone app. I will test a simple app as well in our build environment as well. We have seen this across all three of our development machines (all os x 10.7.3).

Same thing here on a Rails 2.2.2 app:

That's a bit curious - we are using Bundler, but I thought Rails 2.2.2 wasn't aware of it.

Jason and Leif, did you tinker with RubyGems at all (e.g., jruby -S gem update --system)?

Leif,

You can use Bundler with any version of Rails. (http://gembundler.com/rails23.html) It just might not work.

Asari-san,

I didn't make any modifications to rubygems, I performed the following:

rvm install jruby-1.6.6
jruby -S gem install bundler
jruby -S bundle install

See JRUBY-6422, which now that I see bundler involved, should be the same. Should be fixed for jruby-1.6.7.

David: Thanks for pointing out JRUBY-6422 has the same backtrace. You're probably right...the stack overflow issues can end up manifesting in any number of ways, many of them totally baffling (like inability to load JRuby's own classes) since the error can occur at any time in any code.

Marking as fixed in 1.6.7, per David's comment. Anyone want to re-test with JRuby 1.6 head? `rvm install jruby-1.6-head --branch jruby-1_6` should get it for you.
