Rails 2.3.2 and cache sweepers

Ruby JRuby
1

Hello,

I’m updating project to use Rails 2.3.2 and JRuby 1.2.0.
What I have done so far is:

  • updated jruby-complete-1.2.0.jar and latest version of jruby-rack
    (last update 2009-02-26) to warbler/lib
  • followed instructions in http://wiki.jruby.org/wiki/Rails_2.3.2
  • added config.preload_frameworks = true to environment.rb

Looks like everything except cache sweepers are working. When deployed
to Tomcat and trying to use controller that has cache_sweeper
defined, following error occurs:

NameError (uninitialized constant ActionController::Caching::Sweeper):
gems/gems/activesupport-2.3.2/lib/active_support/dependencies.rb:
440:in `load_missing_constant’
…

I found an issue about that
http://rails.lighthouseapp.com/projects/8994/tickets/1977

But the application works with MRI mongrel and JRuby WEBrick and fails
only with Tomcat.
And if I try to run it in production mode with sweeper enabled in
Tomcat, the application hangs when booting, tomcat takes 100% cpu and
runs out of memory while later.

I tried also with jruby-complete-1.1.6.jar and got the same error in
Tomcat.

Is anyone using cache and sweepers successfully with Rails 2.3.2 and
JRuby?

Thanks for the report Miika. Would you mind filing an issue either in
JRuby’s JIRA [1] or JRuby-Rack’s JIRA [2]? This should be fixed for
the next version of JRuby-Rack, which I hope to release soon.

Unfortunately they didn’t help. I have only config… entries in the
initializer block. I’m not sure what else to try.
