Correct. Fixing those bugs are generally pretty simple, because they're
fairly small in functionality.

Well, I feel like a n00b after having realized the most severe problems we're actually caused by the fact that a team member (who is running JBoss locally) had set com.sun.faces.expressionFactory parameter to com.sun.el.ExpressionFactoryImpl. So there was a mixture of two implementations. Sorry for blaming Resin! *blush*

After changing the setting to com.caucho.el.ExpressionFactoryImpl (or rather a proxy using com.caucho.el.ExpressionFactoryImpl if present), the problems turning are much less severe.

I reported http://bugs.caucho.com/view.php?id=5034 (which has a very easy workaround) and http://bugs.caucho.com/view.php?id=5035 (which should be no problem in production, but make development much less effective; trivial to fix so I trust it to be in the next release)


I do want to ask, why Resin is using a custom EL implementation rather than the Sun implementation? Performance? Licensing?

Historically licensing and performance.
