Description

When implementing seam-solder on WAS 8.0 one gets the following exception:

javax.el.ExpressionFactory has final methods! CDI doesn't allow that.

It turns out, that the class javax.el.ExpressionFactory shipped with the IBM Application Server contains a private final method called 'getClassNameSysProp'. This is the method org.apache.webbeans.util.WebBeansUtil.checkUnproxiableApiType() respectively ClassUtil.isFinal() complains about.

Question here is: Is CD really preventing you to define private final methods or should this be reduced to public methods only?

Thanks for clarification.
