activerecord-3.1.0.rc5 from JRuby. Nothing seems to work

I am having multiple problems with jruby and activerecord-3.1.0.rc5.

For example, after i have ran my migrations, I create a simple Role object from the rails console and all is good :

jruby-1.6.3 :006 > r = Role.new(:name => "Standard")
 => #<Role id: nil, name: "Standard", created_at: nil, updated_at: nil> 

I then want to display all Roles so I enter

jruby-1.6.3 :007 > Role.all

I get the following stack trace:

argumentError: wrong number of arguments (3 for 2)
    from /Users/paulcowan/.rvm/gems/jruby-1.6.3/gems/activerecord-3.1.0.rc5/lib/active_record/base.rb:470:in `find_by_sql'

I get this er开发者_C百科ror of:

ArgumentError: wrong number of arguments (3 for 2)

Quite a lot with Rails 3.1r5. The whole thing looks fubar. Has anyone else ran into these problems?

I mentioned something very similar here:

ActiverREcord seems wrecked.

Here is what I am using for my jruby data access:

gem 'activerecord-jdbc-adapter'
gem 'activerecord-jdbcsqlite3-adapter'
gem 'jdbc-sqlite3', :require => false

Anybody else running into these problems?
