Inline plugins do not include i18n messages.properties as expected

Anyone have a working example of inline plugins and message.properties
working properly?

When building our project's war we've noticed "proper" plugins like
hibernate and quartz (grails install-plugin *) will deploy
message.properties in the final war file. This syncs up with
http://jira.codehaus.org/browse/GRAILS-1403 which has this fixed back in
1.1.

For our modularized "inline" plugins we've noticed a different behavior.
The messages.properties are included in the zip produced by grails
package-plugin but the final war does not include the file as expected.
To get around this we've added our messages to the top level project
that depends on the inline plugins (for now at least).

Are we doing something wrong or is this a legitimate bug? We're on
version 1.2 at the moment.

Thanks,

Attached a project showing the behavior. Run grails package-plugin under inlines/hasmessages plugin and then build the war from nomessagesbug/.
