NumberFormat exception when migrating to 1.1

[Travis Reeder]

I get this with no changes other than replacing jars, code is here:

 <h:column>
                <f:facet name="header">
                    <h:outputText value="#{bundle['percentage.short']}"/>
                </f:facet>
                <h:outputText
value="#{campaignBean.percentOfCampaignFulfilled}">
                    <f:convertNumber type="percentage"/>
                </h:outputText>
            </h:column>

javax.servlet.ServletException: Cannot get NumberFormat, illegal type percentage
        javax.faces.webapp.FacesServlet.service(FacesServlet.java:109)
        
org.apache.myfaces.component.html.util.ExtensionsFilter.doFilter(ExtensionsFilter.java:122)
        rhythm.marketplace.filters.AuthFilter.doFilter(Unknown Source)

Any ideas?
