DEPRECATED: require 'arjdbc' instead of 'jdbc_adapter'

I’m developing a new application with rails 3.0.3 and jruby.
Today I’ve found this deprecated message: DEPRECATED: require ‘arjdbc’
instead of ‘jdbc_adapter’.
What does it mean?
I’m using postgres as database.

Somewhere in your application code (possibly in an initializer) you
have code that’s doing “require ‘jdbc_adapter’”. It should be changed
to “require ‘arjdbc’” as of the 1.0 release.

Also note for Rails 3 you no longer need the
config/initializers/jdbc.rb file that got created from the ‘jdbc’
generator.

I’ve noticed that the DEPRECATED message raise only if I create a new
application without using -m http://jruby.org/rails3.rb.
