BigDecimal.to_s('F') does not match MRI, generates bogus formatting
-------------------------------------------------------------------
Key: JRUBY-2567
URL: http://jira.codehaus.org/browse/JRUBY-2567
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.1.1
Environment: jruby 1.1.1, comparing with MRI 1.8.6, OS X 10.5.2,
Powerbook
Reporter: Paul Cantrell
JRuby's BigDecimal.to_s('F') generates output that does not match MRI, and does
not parse as a valid number. Compare:

This is currently breaking the JDBC Postgres adaptor, and possibly other JDBC
adaptors as well. They rely on to_s('F') working correctly, and JRuby's bogus
format causes DB errors on inserts and updates of decimal columns in Rails.
