Upload catalog translation causes an error

Comienza con los puntos de entrada del catálogo de cargas y de la traducción de facturas en la documentación enlazada; después, sigue las llamadas notificadas a través de InvoiceResource.java y LocaleUtils.java. Reproduce la carga mediante el flujo documentado y confirma que una locale como fr_FR ya no llega a LocaleUtils con una barra final ni produce el error notificado Invalid locale format.

The upload catalog translation and upload invoice translation code causes the following error:

org.killbill.billing.client.KillBillClientException: Invalid locale format: fr_FR/

The following stack trace is seen in the Kill Bill logs:
