Hi all!

On one of our airport applications we tried updating to Java 7u40, and all hell broke loose. The most noticeable symptom is that columns added by ActiveRecord migrations are not recognised later in the app.

This has been tested with JRuby 1.7.4 and 1.7.5.dev (2013-09-11), on Linux, Windows, and OS X.

Turning off InvokeDynamic restores normal behaviour.

I thought I'd ask if there are known issues with InvokeDynamic and/or Java 7u40 before spending time on reproduction.

Are there any known issues with JRuby and InvokeDynamic and/or Java 7u40?
