$ rvm use 1.7.25
Using /Users/plundberg/.rvm/gems/jruby-1.7.25
$ bundle exec irb

jruby-1.7.25 :003 > quit
The failing code (https://github.com/jeremyevans/sequel/blob/master/lib/sequel/core.rb#L139) looks like this:
def self.extension(*extensions)
extensions.each{|e| Kernel.require "sequel/extensions/#{e}"}
endAny ideas or suggestions on what change in 1.7.26 could have been causing this?
