  Deploying JRuby/Rails to Glassfish: undefined method `bundle_path' for Bundler:Module
  
  The following error shows up in my Glassfish log when attempting to access my app:
  Caused by: org.jruby.exceptions.RaiseException: (NameError) method 'to_yaml' not defined in Object
  
  Looking through the log I see this:
  undefined method `bundle_path' for Bundler:Module
  
  I confirmed that warble is definitely putting the Bundler gem in my .war file.
  (using ruby 1.9, rails 3.1, glassfish 3.0 and 3.1)
  This also appears in the glassfish log:
  Policy Provider:Failed Permission Check: context (" myapp/myapp ") , permission (" (java.lang.reflect.ReflectPermission suppressAccessChecks) ") |#]
  
  However I've verified that the permission is granted in server.policy. 
  EDIT: I fixed the permission problem and the first two errors persist. (That said, the premission problem required me to edit a file it specifically says not to edit. Attempting to grant this permission in server.policy in Glassfish did not work).
  Here is the relevant environment info from the Glassfish log file: https://gist.github.com/1245825

  This affects some application servers but not others.
  See this thread for further information and a quick fix.
