SQL Syntax Error with Jruby under EngineYard - sqlite

Question

I am having some fun with Jruby, but I am having troubles getting my app deployed on EngineYard. Under deploy I am getting the follow error:
ActiveRecord::JDBCError: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '(2147483647) DEFAULT NULL' at line 1: ALTER TABLE `iterations` CHANGE `points` `points` longtext(2147483647) DEFAULT NULL
Even though my database.yml uses SQLITE and not MySQL. The migration file is listed as:
class ChangePointsToLongtext < ActiveRecord::Migration
def up
change_column :iterations, :points, :longtext
end
def down
change_column :iterations, :points, :text
end
end
I am almost certrain its the change_column - I have tried t.change and looked around for other syntax changes. I think it may be an issue with the Jruby version running on EngineYard - which I can't update.
My GemFile looks like this:
platforms :jruby do
gem 'jruby-openssl'
gem 'trinidad'
gem 'activerecord-jdbc-adapter'
gem 'activerecord-jdbcmysql-adapter'
gem 'jdbc-mysql', :require => false
gem 'jdbc-sqlite3', :require => false
end
So I believe I have all the relevant gems loaded in order to establish a database under Jruby, although I may be very wrong! I think I just need an alternative to change_column
Has anyone run into a similar problem? Or have any advice on changes? any help is always much appreciated!
Thanks

First, please use https://support.cloud.engineyard.com/ if you need help with Engine Yard.
Second, EY does not support SQLite. When your application is deployed to EY, EY will replace database.yml with appropriate information so that your application can use DB indicated in the environment configuration. The DB choice should default to MySQL when you set up your environment.
And finally, it appears that something is generating the incorrect SQL statement. Seeing that a similar migration works with MRI and mysql2 adapter, the issue probably lies with JDBC adapter. You can open an issue at https://github.com/jruby/activerecord-jdbc-adapter/issues or http://bugs.jruby.org.
