Rails 3.2 activerecord-jdbc-adapter错误

Question

我刚刚更新到在JRuby-1.6.5上运行的rails 3.2，当我运行rake db：migrate时，我收到以下错误：

  

未定义的方法`accept'代表nil：NilClass

这是跟踪：

错误似乎来自activerecord-jdbc-adapter。

我在我的gem文件中引用了master：

gem 'activerecord-jdbc-adapter', :git => "https://github.com/nicksieger/activerecord-jdbc-adapter.git", :branch => 'master'

是否有其他人有此错误或有解决方案。
