has anyone figured out how to use resource bundles in a portlet ?

I configured my portlet.xml to use a rb:

<portlet-name>Blah</portlet-name>
....
<resource-bundle>com.blah.Blah<resource-bundle>
<portlet-info>
Title
<short-title>Short Title</short-title>
keywords
</portlet-info>
....

I added
web-inf/classes/com.blah.Blah.properties
web-inf/classes/com.blah.Blah_en.properties
web-inf/classes/com.blah.Blah_fr.properties

with content like
javax.portlet.title=english Blah
javax.portlet.short-title=The Title
javax.portlet.description=dunno
javax.portlet.keywords=blah, more blah


When I call getResourceBundle(request.getLocale()); inside a doView (the browsers locale is en) I get a bundle, but it's locale (rb.getLocale()) is null, and I get the entries from the descriptor no matter what (not the ones from the rb) via rb.getString("javax.portlet.title");

commenting the values for title etc. in the portlet.xml leads to exceptions at runtime, like:
java.util.MissingResourceException: Can't find resource for bundle org.jboss.portal.common.util.ParentChildResourceBundl
e, key javax.portlet.title
at java.util.ResourceBundle.getObject(ResourceBundle.java:326)
at java.util.ResourceBundle.getString(ResourceBundle.java:286)
at javax.portlet.GenericPortlet.getTitle(GenericPortlet.java:87)

I also tried to use a ListResourceBundle with the same results.

What am I missing ?
