Subject: Jruby precision issue with reading float values in mysql db

Hi,

I was trying to upgrade from 1.1.6 to 1.2.0 and noticed a strange
issue with floats. In Jruby 1.2.0, a float like 2.52342 is read as
2.52342009544373 from the DB.

A few steps to reproduce this.
1. Migration:     t.float :reading
2. Fixture:        reading: 2.52342
3. Run script/console

jruby script/console
Loading development environment (Rails 2.2.2)
>> Foo.first.reading
=> 2.52342009544373

Any idea if this has been logged as a bug or if there is a workaround?
