I am seeing the exact same problem with a Rails 4.2.1 application in development environment. I have added a migration to add a uuid column, and the migration fails because...

For what it's worth: Adding a simple `ActiveRecord::Base`, to initiate ActiveRecord class loading, before [this line](https://github.com/jashmenn/activeuuid/blob/master/lib/activeuuid/patches.rb#L155) solves the issue for me in Rails 4.2.1.

@rsov / @ kares : any chance this fix can be merged soon? Using the branch for this PR locally in our (JRuby 9.2.0.0) project appears to resolve the issue....

Thanks so much, @rsov ! @kares : any chance this fix is acceptable, so that warbler can support JRuby 9.2.0.0?
