> Upgrade from commons-digester to commons-digester3
> --------------------------------------------------

> Key: VALIDATOR-499
> URL: https://issues.apache.org/jira/browse/VALIDATOR-499
> Project: Commons Validator
> Issue Type: Bug
> Reporter: Ric Harris
> Priority: Major
>
> It would be useful to be able to upgrade dependencies from
> {{commons-digester}} to the slightly newer {{commons-digester3}} which will
> likely receive further updates as commons libraries progress.
> However because the class {{FormSetFactory}} extends an abstract class from
> {{commons-digester}} this will require a new major version due to the
> incompatible change in the class hierarchy
> i.e. from
> {code}
> FormSetFactory extends
> org.apache.commons.digester.AbstractObjectCreationFactory
> {code}
> to
> {code}
> FormSetFactory extends
> org.apache.commons.digester3.AbstractObjectCreationFactory<FormSet>
> {code}
