ear中带有JRuby rack的多个war web应用程序

我正试图将两个与warbler捆绑在一起的JRuby Sinatra web应用程序（运行时1.9）打包到一个ear文件中。在glassfish（2.1.1或3.1）中部署后，我发生了一次崩溃

JRuby.jar、JRuby-stdlib.jar和JRuby-rack.jar都可以在这两个应用程序的类路径中访问，如果我只保留其中一个，它们都可以正确部署。但如果我留下两个，则在机架启动期间，第二个始终会因错误而在部署时崩溃：

根据错误，第二个应用程序似乎使用了1.8 rubygems，原因我不明白：

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

我的代码中没有“rubygems”之类的要求

我的gemfile.lock是

提前非常感谢。

在glassfish中，默认情况下jar文件在war应用程序之间共享，而jruby rack似乎不喜欢到处共享

在我的例子中，需要对sun-web.xml进行一些更改来隔离类加载器
