I’m trying to pack two JRuby Sinatra web apps (runtime 1.9) bundled with warbler

I’m trying to pack two JRuby Sinatra web apps (runtime 1.9) bundled with warbler into an ear file. After deploying in glassfish (2.1.1 or 3.1) I have a crash.

JRuby.jar, jruby-stdlib.jar and jruby-rack.jar are accesible in the classpath of both applications and both of them deploy correctly if I leave only one of them. But if I leave them two the second one always crashes while deploying for an error during rack startup:

Based on the error, it looks like the second application for a reason theat I can’t understand is using 1.8 rubygems:

require at file:/usr/local/glassfish/domains/myapp-domain/applications/j2ee-apps/myapp-server/lib/jruby-stdlib.jar!/META-INF/jruby.home/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:36

There is no require ‘rubygems’ in my code or such.

My gemfile.lock is

  remote: http://rubygems.org/
  specs:
    haml (3.1.6)
    jruby-jars (1.6.7.2)
    jruby-rack (1.1.7)

Looks like by default in glassfish jar files are shared between war applications and looks like jruby-rack does not like being shared all around.
